Le Tigre summed up in a word: WEIRD.
But that's the point, right? Located in a strip mall-ish building in a somewhat out of the way location - at Verona Road and the Beltline and right next to a hardware store, it ought to be weird if anyone's ever going to go there.
Dark, kind of musty and with, obviously, tons of tiger themed or printed everything, this place is interesting to check out sometime in sort of a touristy way.
I don't recommend getting a mixed drink. My G&T was the weakest, most tasteless I've ever had. But if you're in the mood for something different and low-key, go and have a couple of beers at Le Tigre.
Or don't. You're not missing all that much.
