I make the yearly trek every St. Patty's Day to wait in line and spend some time in this bar. It is always worth the wait to get a good pint and watch some dancing.
Other than St. Patty's Day, this bar is a great place to meet friends and have some rib sticking meals. On busy days it can be hard to catch the wait staff. It is a great place for a couple of rounds of beer with a few friends, things can get busy and noisy quickly. This bar seems to be the favorite of graduate students taking some time away from research and teaching.
