During our 1 week vacation to the Toronto area, this was by far the best restaurant my husband and I ate at. The atmosphere was very nice. It was a little dark but there were candles which gave a beautiful ambiance. Our server was awesome. We came in wearing jeans and tee shirts (we didn't know when we left that we were going to decide to eat at such a nice place) and our server didn't treat us any differently than if we had been dressed to the nines.
It was a little pricey but the food was amazing. We each ordered a steak and lobster dinner and we were both in food heaven. All in all it was a really nice treat and definitely worth the little extra money. I would definitely recommend The Keg if you are looking for a nice evening out.
