I've only been to Mary O'Neill's a couple of times for drinks and apps. The apps are pretty good, definitely better than your average bar food. They are almost always packed so finding seats in the bar area is difficult and it's a very small space so typically standing room is limited as well. The usual crowd that is there is very friendly and easy to talk to if you are looking to spark up a conversation. Last time I went the place smelled great, although every time the kitchen door opened huge clouds of smoke seeped out. I don't understand how the staff good see or breathe! All-in-all I like the place and will continue going. Hopefully, next time I'll try some dinner menu items.
