C'est What is arguably the best place to hang out in the St. Lawrence Market area. As it has a number of great things going for it.
-) First it is somewhat close to transit.
-) It does not get horribly packed like the Bier Market
-) It is great for large or small groups.
-) Depending where you sit it is a great place to take a date
-) If you are a beer lover you will like the pretty vast selection of brews
-) Has a bit of that Montreal, basement, exposed brick, chilled vibe AND a fireplace.
-) Food is not bad at all. However not the best Toronto has to offer but it will suffice.
-) Some nights there is live music, check your listings.
-) Pool tables.
I like it for its laid back decour, vibe and a lack of pretentiousness. Wine selection is alright and most pints will start you off at around the $7+ mark. Which for this hood is pretty standard.
I like how they are more like a multi-purpose venue, so I would not call this place a pub since it does not have any of that British/Irish... well English vibe that say the Firkins have. Which is nice and different.
Definitely an institution in the hood and a great place to come with friends and just hang out and chat. I highly recommend this popular place.
