There are two types of Irish bars when it comes to atmosphere. Those that go for the rustic beat up chic, and those that go for the upscale dark paneling low light style. Erins is the latter.
There are also two types of food in these places. Those that serve Irish Irish food (blech, Irish food sucks) and those that serve americanized Irish food (meh, its ok) Erins is the latter.
They all serve Irish beer and whisky.
So that is Erins. Meh, ok food, in a very dark clubby type atmosphere. If its what you want, its fine
