We were staying at 124 on Queen and luckily had made reservations in advance (recommend you do too if you'd like to eat here!)
Simply put - the food was incredible. Locally sourced, farm-to-table style - the freshness of the ingredients and innovative dishes made for an epicurean delight! We had the scallops and pork-bellies to start - perfectly cooked and the flavors were amazing. For entrees, we had the lamb and the white fish with lobster - its was REALLY difficult not to lick the plate when we were done. ;-) Flawless execution - kudos to a great kitchen team.
Excellent service by friendly, knowledgeable staff who took the time to review the ingredients while serving. Great wine selection from local wineries - I have found a few new favorites.
We had looked at the menus of various places up and down Queen Street and the prices were all a bit too high for the offerings - but it's a tourist strip, so to be expected. The prices here are comparable to those, but the food is leagues above what you will find at the others.
I live in Toronto and I will probably drive down to have dinner here again one day soon - it was that good. Don't visit Niagara-on-the-Lake without having dinner here.
