I see a lot of reviews on the food, and they are typically not very good. What do you want in an Irish pub? Has anyone ever had excellent food at an Irish pub? The Irish are known for POTATOES! What do you expect?
All that said, I think O'Shea's does a good job with the materials they have to work with. The fish and chips is excellent (get the haddock), and it is only $10 on Thursdays. The draft beer selection is very good (Smithwick's on tap!).
The atmosphere is good, and the staff is pretty friendly. Need to talk to "once in a while" patrons more often and let the regulars fend for themselves. ;)
