the Irish Pub is the best bar/pub in Atlantic City and anyone who disagrees doesn't really know what they are talking about, or they are probably a tourist from out of state. the Pub is open 24/7 so you can always stumble in @ 3am after a night a gambling in the casinos. they also have pretty good/cheap bar food. and they even have rooms available if you get too drunk to drive home.
Pros: open 24/7, good bartenders, good bar food
