Fantastic beer selection. Only a handful of taps, like 6 or so, but a nearly endless selection of craft bottles. And the also seem to have the best pizza in the Tremont area. If you are getting a slice, try the pepperoni and drizzle some honey on it (honey packets are $0.25). I know I know, it sounds insane, but the bartender convinced me to try it and I can't go there and not do this! It's insanely delicious.
The bartenders have always been very friendly and helpful if you are looking for a beer recommendation. Also, very nice patio out back and on a nice summer day I recommend playing darts on their patio dart board (though bring your own chalk, they are frequently out of chalk).
Overall, just a great bar.
