Although it is kind of pretentious, it's a great spot to grab a decent drink with a date or a few friends.
I can't speak much for the wine, but they do have a great beer selection. Some on tap, or go pick one from the fridge, there's a beer for everyone. The bartenders are nice too! I usually prefer a divey, old-people bar with cheap beer, but when I want to spring for something a little classier, La Cave is the place to go.
