A great patio, you can bring your own food (namely, your order from The Grilled Cheese delivered to your table), cool vibe and respectable variety of beers on tap. Interesting people all over the place. Awesome bar for people watching.
Here's a tip: patio spots are hard to get, but sit inside and keep an eye out. Once a table vacates, you have to pounce on it.
It's a hipster bar that doesn't make you feel self conscious if you aren't a hipster. But don't wear a suit. C'mon, you got to meet these people half way.
