One of my favorite bars in the city, even though I don't get here enough. Sorta has a hipster vibe, but not in a pretentuous way. They have daily drink specials and a nice selection of beers on tap. The bartenders are nice, the patrons are friendly and even if you come alone you will have a bunch of new friends by the time you leave.
Kelly's sort of feels like walking back in time. a 50's diner feel, dark, and cozy. The back porch is a great place to hang out on warm nights but fills up quickly.
Get the mac and cheese if you are hungry. It's stellar.
