Stumbled upon this place with my boyfriend. The gentleman who seated us was quick, attentive and sat us at a nice private table around 9pm. Atmosphere is great and decor is beautiful. Open concept kitchen is awesome. I ordered red wine which was good, boyfriend ordered an old fashioned which was very underwhelming. Needless to say I don't think that... More

Food was amazing ( I had the duck) and the waiter was kind and helpful with wine choices (but maybe a bit TOO attentive?). The appetizers and desserts were also good. 4 stars because it was a 100$ meal for 2 people even with their 25% discount. Great place though, nice and quiet at least on a tuesday night :p

Deciding on a place to eat in Downtown Waterloo - my recommendation is to avoid King Street Trio. Have been there on a couple occasions now. Steak was overdone, potatoes were "coolish/cold" and the wine was extremely flat. The restaurant is only open evenings and the seating is limited - you would think the extra attention o detail would result... More

The food here is absolutely amazing. I've been a few times before, but the food this time was really exceptional. I had the glazed mackerel and my partner had the 1/2 rack of lamb. Both were delicious. We shared the cheesecake for dessert, which was just about the best cheesecake I've ever had. The only critique I could offer would... More

Have been a faithful regular customer at King Crab, so when it closed we thought we would be more regular at King St. We went for our anniversary last month and was very disappointed, We both ordered 2 of the more expensive items on the menu. Both had lobster in them. They were terrible. Very little lobster and the lobster... More

I have passed King Street Trio countless times, but it wasn't until recently that I had a dinner there. I was pleasantly surprised by the decor and ambiance. To start, I had the watermelon salad. It was good, but I think it missed a punch of something (not sure what). I had paella for the main and it was delicious.... More

Came here with a Groupon deal. I really like the decoration here. The lamb rack was cooked perfectly. Also, like the cheesecake which is made in a different way than usual. Food is pricy here. But I would come back in the future for sure.

Had a very enjoyable dinner @ King Street Trio. The daily feature soup was out of this world delicious. Coconut shrimp, calamari and risotto were all very good as well. The main - King Crab on gnocchi was just ok, good flavour, but the crab was over done and left something to be desired. I would return and recommend as... More
