I like Snakes and Lattes. They have an excellent and wide range of boardgames to choose from and the price is accessible (5$ for unlimited play). The game geniuses are awesome. They are able to explain EVERY game. This is a great place to spend time with friends and try some new games before you purchase.
Downsides: It's popular, so quite busy. Also, the baristas (not the game geniuses) are all hipsters and not quite friendly and a bit condescending, but your interaction with them is limited.
Side note: Why is it that most baristas (not just here) are such A-holes? Seriously?!?! Can someone help me out with this fact?
