Abbey Theatre, Via del Governo Vecchio 51
Hello man (I'm talking to the guy that reads this)!
The Abbey Theatre is my favorite Roman (Irish) Pub. It is the other place where I usually go for Pub Quizzes, but I have also been there just for a beer or a quick meal followed by some chit-chatting.
It is a very cozy place. Yes, this means that it is not huge, but you would be amazed to see the amount of people you can fit in there. I have seen it very, very crowded, and not only in Pub Quiz night. It is mostly frequented by international crowds, although lots of Italians go there too, especially on football nights, for a Juve-Milan derby or something.
Some of my biggest and best friendships have either started or developed there. A pack of 4+ people around a tiny round or sturdy square, big and diner-like table drinking their Lagers or Blacks is definitely my preferred social gathering :) Either with long-time friends or people you have just met (and this is as literal as it comes), the Abbey Theatre offers you a somewhat dark but very comfortable atmosphere, emphasized by the Irish National Theatre inspired or even copied decorations.
Offering a wide array of food choices, you can easily dine or lunch there if you want a quicker, convenient and relatively cheap meal. It can be accompanied by one of a huge selection of beers, with Guinness at the top of the list. In the end, be it in one of the tables at the back, or in one of the narrow corridors by the counter, you can also go for an Irish or not-so-Irish spirit.
Oh, and if you are into sports, they show Rugby, English and Italian soccer and most American sports. It's one of the top places to be if anything's happening in the sporting world!
