"Welcome to Moe's!" rings out throughout the restaurant everytime the door opens. This does get a bit annoying, but once you dive into your food, you'd be willing to put up with just about anything.
This is the Subway of Mexican restaurants - you get to choose what ingredients go into your food selections. Two of us had the Billy nachos, and the rest had burritos. The burritos were quite large and tasty. The cheesy sauce on the nachos is almost good enough to NOT want anything else on the chips. We ate ourselves beyond full as it was just too good to waste any.
