I don't drink... but Seamus' is an alright place in my book. We dropped in after a DBack's game the other night, and I was seriously about to chew off my own arm I was so hungry (and nothing else was open within walking distance... at 10pm... after a baseball game...in the 5th largest city in the nation. Seriously people.).
Seamus' came through for me though - even though the kitchen was about to close and they were only serving apps... I was able to find something veg to eat - Potato Skins, sans bacon.
The service was acceptable overall, but the waitress went out of her way to make sure that I was happy. When the skins came out with bacon, she had the kitchen remake them right away.
I had to knock off one of the stars because Seamus' is a little bit dirty. Old bar dirty, not anything to be completely grossed out over... but still.
Go here. If you drink, have a pint. Try some food (if you get there early enough).
