I've eaten here five times in the last three years or so, and my experiences with the food have been pretty mediocre. We've come back so often because my fiance has a huge weakness for the Guinness Stew-- well, or HAD. Â The last two times he's ordered it, the stew has been extremely oversalted to the brink of being inedible. Â I'm no expert, but I've been to Ireland a couple of times and I wouldn't call this super authentic.
I threw in an extra star, though, because O'Connor's does carry-out, and sometimes you don't want to cook. You just want to swing by on the way home from work and pick up something for dinner that isn't fast food. O'Connor's carry-out has always been fast and reasonably fresh; we call to order, ten minutes later we pick it up. Â Can't argue with that.
The beer selection is also really nice.
