I'm a big fan of Beerbistro and a regular patron. The beer selection is great and the food is really good too! The food is really what brings me back as there are a lot of bars in Toronto which offer a wide variety of beer.
The mussels at beerbistro are delicious! I've tried all of them and highly recommend the Spicy Thai, Devil's Puttanesca and New England Mussels (in that order).
