This place is like the Applebees of Irish-themed Mexican food, which right there means it's pretty much stuck at 3-stars for me.
The service was good - pretty standard. The food was good - not exceptional. They do have a separate 'healthy' menu, which was appreciated since when I go to eat Mexican food I generally stuff refried beans and salsa into my gaping maw until I can't get out of the seat. The margaritas were pretty good. Over all, no complaints. It's just a very generic, non-special atmosphere, and nothing over the top.
Swing by for lunch or dinner or whatever. Don't bring a date here.
