We visited the Museum Tavern last night and had a fantastic time - It was my husband and I's anniversary and I had passed by this place a million times when I was a U of T student, always wanting to try it.
We were given a nice little corner booth, which allowed us to have an intimate experience. The servers were all very approachable and professional. I had the Aztec Bowl, which was DELICIOUS and a very well-balanced meal. My husband had the Short Rib French Dip, which was one of the best he's ever had. The ambiance is very cozy, and clearly a lot of thought was out into the decor. We kept noticing little accents reminiscent of the 1930's and gave us all kinds of ideas for decorating our own home!
The only things we were disappointed in were that the service was a tad too slow for our liking. We had to wait a long time for a refresher on our drinks, and for the bill at the end of the night. Given that it's more expensive than your average place, I expect that to be reflected in the service. Also, the Cider selection (if you're a fan, like me) was inadequate. They only had Waupoos, which I find too sweet and light.
Besides those two small issues, we had a great time and will definitely return! Highly recommend.
