Excellent food and service! The ambience is great and the décor highlights details of the 100+ year-old building and incorporates local reclaimed wood. When you come, make sure you try their Vanilla Panna Cotta for dessert... just awesome! Definitely recommend this place!

Always such a pleasant experience at King Street Trio. Fine dining with unpretentious, super friendly service. As a foodie and lover of new experiences, I rarely frequent the same restaurant repeatedly in a year, but I certainly do with King Street Trio. I always trust that I will have an exceptional time. Thank you for making our Mother's Day Dinner great!

Great table service. We go to KST for the food. It is high quality and excellent in taste. Caesar salad is one of the best. A great app place for special celebrations.

I had the zucchini linguini and found it quite bland. Was pretty disappointed. I had to put salt and pepper on it just to give it a bit of flavour.
Found it strange that in the bathroom they have soap dispensers with cheap soap and paper towels. I would think that a place like this should at least have cloth towels and fancier soap. The look of the bathrooms really throws off the ambience of the entire restaurant. The stalls are super ugly.
When the waitress brought us our check, she left those red and white mint candies that they give out at East Side Mario’s and Boston Pizza. In my opinion, these candies are worse than giving nothing. Should have some kind of mint chocolate stick at least.

The service was great ,food was great ,decent portions ,best dessert i ever had

Took my husband for his birthday yesterday, and so glad we chose King Street Trio! The menu was exciting, packed with things I'm dying to try. I wound up having their 6 oz. feature steak, and my husband went with the 8 oz. filet; I'm not sure either of us have had a better steak! You can taste the difference quality ingredients make, particularly in the hands of a skilled chef.
The only thing that would have made it even better was if there had been a local beer on tap!

My wife and I have been coming to Brian's restaurants for over 20 years, always a special treat. From the welcome at the door, to the attentive service, and the great food by Chef Kyle, it was a very wonderful evening. Always a good time, and we are looking forward to the Spring tasting menu later this month. Keep up the great work!

What a wonderful experience we had this evening! From the moment we walked in till the time we left we were treated like royalty. We were there for our anniversary which they congratulated us several times and even added a sparkler for our dessert. The wonderful wait staff member was knowledgeable with wine selection suggestions and food suggestions. She looked after our needs before we had to ask. The food was cooked perfectly and tasted fantastic. It was our first time there- we will definitely be back!

Another great meal at King Street Trio. Always enjoyable.

Oysters are my favorite here. The new Ontario lamb dish is a winner! The Filo wrapped fried cheesecake rounds it up nicely! My wife and I are regulars here. A little pricey when all is said and done but a real treat for that special occasion.

I am a big fan of this restaurant. However, I must say I was a little disappointed with the food this time. Three of us went, I got the lamb special and the other two got the chicken. Chicken portions were good however, when I saw my plate come out, my first thought was I have to stop for take out on the way home. It was far too small. Very tasty though. NOW, if you are going to serve creme brulee, it needs to be perfect. This creme brulee was like a custard. Too thick and too heavy. I never pass up creme brulee if it's on the menu. I will be back. Service was awesome as usual.

Always a spectacular meal with exceptional staff. Very friendly atmosphere with Brian greeting and seating each guest and then strolling by to see how our meals were.

A favourite local restaurant of mine.

Food was great and service impeccable as always. A favorite of my husband and mine.

The staff was very friendly and attentive. Great presentation of the entrees and the food was delicious! My husband had the rainbow trout and Imthe pork loin. A great way to celebrate a birthday.

Never been disappointed at King Street Trio. Would highly recommend for a nice evening out. The owner goes above and beyond to make sure you experience is the best.

Food was very good. Wait staff was very professional.

My husband and I went out on a date night, and though we enjoyed our meal overall we wouldn't rush back.
The service was almost laughable - owner and server were too attentive in some ways, actually explained to us how a restaurant and ordering worked and read us the feature menus that we had been handed and reviewed in detail (hello - we know how to read and even when we commented we had fully reviewed it they kept going). If they dialed it back a little without hovering it would have been nicer.
Calamari was very disappointing as were most of the sauces with the dishes, lacking flavour. The steak was too chewy, the pickerel wasn't cooked as well as it could have been and the sauce tasted too heavy of bacon fat.
Deserts were average - panacotta was not worth the $.
Though we had a decent night I would consider food average at best. With so many other great options in the region it's unlikely we will return or recommend.

A good place for a date dinner a very lucky plac

Has become our go to resturant for dinner in downtown Waterloo. Food is always great. Staff is friendly and work well as a team to ensure you have a great meal.

Delicious food, quiet atmosphere, and a most attentive wit staff. A gem for Waterloo!

Never disappoint, great service and the food is superb

Food here is done very well and precisely - Easily the best mac n' cheese I've ever had (part of the King Crab Platter). While most mac n' cheese tends to be on the heavier and greasier side, King Street's take is delicious bite after bite until there is regrettably none left. My partner ordered the rib eye which was executed perfectly, another wonderful entree. Our plates were clean. Service was efficient and food comes out pretty quickly (great for us). I love my dessert (filo pastry cheesecake) which has a wonderful texture and just a touch of sweetness.

Don't judge this place by it's exterior! It does not look great from the street but inside it goes upscale very quickly. Well laid out comfortable, great service and excellent top end food.

Came on a Monday which provided 25% off you food bill just because! The place was not only packed but the service was still super attentive and fun. All the serving staff had smiles on their faces. Got to sit directly beside the kitchen and see the chefs work which i think was the best seats in the house. The presentation on the plates made them almost too pretty to eat. I've come before for dinner here with family evenings and they never disappoint. Definitely going to go enjoy another evening out at King Street Trio in the near future.

Ordered 2 entrees only with little delay. Wrong wine brought to table. Then waited over 30 minutes for food to arrive. Chicken dinner was decent; seafood was lacklustre. Carb was a piece of French bread with a pesto spread; squid was rubbery. Server was nice enough but the kitchen let her down. The 25% off Monday discount might make it worth an overall Fair.

Being greeted both upon arrival and departure by the owner was most impressive. The service was outstanding and the food was very good.

First their appetizers escargot fricasse, bakes apple brie were simply wonderful. Tried their ossobucco, porkloin and they were delicious and a good size portion. Key lime pie meringue at its best!

Awesome experience totally recommend it to anyone

Food and drinks were fantastic! Service was friendly and professional.

Food and Service was very good. We were there 4hours and enjoyed every minute!

It was a very good meal nothing else needs to be said. Come out for mar 22 cooking presentation - it’s lobster night :)

We had an amazing first experience at King Street Trio for our Anniversary. Having the manager/ owner at the front door to greet everyone, check in on your meals and say good-bye as you're leaving made it feel like you were a guest at this chic restaurant. Every bite was amazing and there was no need to ever ask for anything- the service was great! We had the oysters to start, the new local, hormone free steak and hazelnut flourless brownie for dessert.

Great food, atmosphere and service. Will definitely go back.

Amazing service, great food, and very attentive staff. The cheesecake was absolutely amazing, I'd have to go again just for it. Steak cooked perfectly as well. We went for a special occasion and they even added a sparkler to the cheesecake - very nice touch.

Went for drinks after a movie and ended up getting some apps. Food was great but they could have staggered the apps a bit more then having them all come out at once. It just seemed to be very rushed. Otherwise a great place to eat and will definitely be back!

This may be my favorite restaurant in the Waterloo area.

King street trio is the whole package. A great atmosphere , delicious food an attentive staff. Will definitely go back!

This place was great. One of the best Steaks I’ve had in the city. Great atmosphere and our waitress was awesome. We will be back.

fantastic night on Valentine’s Day! Food was delicious and ambiance was so romantic ! I have recommended many friends abt this restaurant.

Valentine’s Day dinner, very busy and great value
