All around a delight!

King street trio is great for atmosphere, food and service! The only reason it isnt getting 5 stars is because every time I have gone in there and they are frying, i start coughing a lot because it is an open kitchen and all of the smokey air goes out into the dining room and is unpleasant. but... read more

I loved everything about the King Street Trio. We'd heard great things about the restaurant, but only had a chance to visit recently. The decor is upscale industrial. High ceilings, black and silver... just loved it. We sat at a table right beside the prep and cooking area. The Executive Chef and others talked with us throughout the meal. It... More

My wife and I ate here on a Monday night. We were quickly seated and the server acquainted us with the menu. Our order was taken fairly quickly and my wife was brought two tasting of different Chardonnays so she could select the most appropriate for the steel head trout, which she declared to be delicious. I selected the Osso... More

I should start by stating I was hoping to email the restaurant directly and privately with some feedback, but unfortunately there is no email address listed on their website. Went for a Friday dinner, party of 5, 2 of us celebrating birthdays. The place is beautiful inside. Our server, while Im sure a very nice person, spoke so softly it... More

While the food and service are terrific, we will never eat here again. The owner has a habitually refused to pay servers and kitchen staff their wages and/or tips using myriad excuses. In some cases even bouncing cheques once he does offer the money up. We've spoken to 3 ex-employees still owed money from 5 MONTHS AGO. If you pay... More

Went here with my fiance and I wasn't disappointed at all. The host was friendly and accommodating. The waitress was cheerful and attentive. The chef was bang on with his creations....... The only problem I encountered was a spicy tomato sauce (which was not indicated on the menu) with my stuffed chicken. I am not able to eat spicy for... More

My wife and I dined at King St Trio last night. When we arrived we were promptly greeted by the owner and table was waiting for us. Our server quickly came to take our drink orders and explained the menu to us. They have many nice Ontario craft beers along with some of the major brands as well. All in... More

My wife and I went here for a Valentines dinner and we were not disappointed. The menu is diverse, but concise enough that you can be confident they have put thought into each dish. When we were there, they had a gourmet slider appetizer as a special. We shared it, and it was delicious. The rice ball was also amazing,... More

Fantastic food, convenient location, professional yet not "stuffy" service, and great atmosphere. In my opinion, the consistently high quality of food, value for your dollar, and "versatility" (great for romantic dinner, party, or just a great meal) can't be beat. In an area with limited options for higher-end dining, I'm so surprised this place isn't at capacity seating every night.

This restaurant is a treat for me and my boyfriend. We usually go eat here for our anniversaries or other special occasions. The food is really good but I would say it's overpriced because the portion is not very large. I suggest buying a groupon for King Street Trio (you get 50% off!) if you're on the budget but wants...
