We have been to Montezuma's, and it is excellent. Appalachian Brewing, Montezuma's and Gary Owen are our favorite G-Burg places.
I hope the place they are building does not close out the place we like in Hanover. I think the Hanover place is called El Rodeo. El Rodeo has a great Frozen Margarita selection though you have to be careful not to order one with two flavors as it is a double and is both $14 and a designated driver required drink.
