O'Shea's was kind of dump. Ok...it is a dump, but everything is cheap, there were a ton of tables and there was a food court that we didnt need to venture toward, but, it's there. The down side is that it attracts the type of clown that I normally like to avoid...douchebags full of liquid courage. We didnt spend a ton of time here, but we were served 2 drinks in about 8 minutes so that was ok. The tiny gentleman that was howling on the mic out front makes no sense to me even if he is dressed like a Leprechaun.
All in all, I'd have no problem spending half a day here and taking advantage of the low cost.
