St Pat's Day in Tampa?
It will be mobbed beyond belief, but the best Irish bar in the Tampa Bay area is 4 Green Fields on Platt Street near downtown. Thatched roof, Irish bartenders, good food at reasonable prices. But as I said, mobbed on St. Pat's. But any Irish place you try in town will be like that, so you may as well plunge in and enjoy the best. Go early, stay long, you'll love it.
