F. O'Mahony's

This place is a small neighborhood bar, but easy to work from during down hours. I would count out Fri/Sat evenings (and game days) for working as it can get really busy. Sundays can be quite slow depending. I've worked from here without problems and you might find a few others with laptops as well. They sometimes have coffee but it's average (standard coffee machine) but the food is really good. (And so are the people)
