C'est What is one of Toronto's hidden treasures. They have a beer selection comparable to Volo or Beer Bistro, but with much more reasonable prices and a very cool atmosphere.
Hidden below the street with a modest entrance upstairs is a large and excellent space with a cozy feel, a functional stage, pool tables and two well-stocked bars.
The food here is always excellent, and it's not just pub fare, you can get roti, thai curries, peameal on a bun. It's all reasonably good, and most dishes come with C'est What's legendary frites. They also have excellent vegetarian options including a Moroccan Stew that is fantastic.
C'est What usually has a solid crowd, but you can go almost anytime for dinner and not wait for a table. It's also a great place to go with a group. Give it a try, you will not be disappointed.
