there are very few pubs in rome, its not like ireland at all, they are more restaurants, the only pubs there seem to be irish or british themed, there is the trinity college just off the main shopping street via del corso, there is also finegans a few streets away from the colessium, these are all in walking distance, they all shut before 2, there are a few disco bars across the river in traversetere and a night market, its worth a look, any taxi will take you there, u will have a ball though, the city centre is the safest place you could go to and people are really friendly
