I've been to Snakes and Lattes twice and we're 1-for-2 when it comes to getting good game suggestions. The staff are definitely very knowledgeable about the massive library of games and are willing to spend the time with each individual table to go over all the rules. You can tell how much these guys/gals love their board games.
Of course, since it's unique in Toronto, the wait time to get in is usually ridiculous. But there are some great places to drink.eat in the area, so both times we got on the waitlist early and just had dinner and/or knocked back a few brews while waiting for a text message from S&L staff.
The place is licensed now so you can get a selection of bottled beer, including a few options from Unibroue (i.e. Maudite, Blanche de Chambly). They also have lots of baked snacks if you get peckish.
$5 cover isn't a bad price to pay for unlimited board-gaming. Just make sure you double-check with the staff that the game isn't too complicated for a group that's already half in the bag.
