As far as fast "Tex-Mex," it's great and reasonably priced. I go here a lot (2/week for years) and the service is almost always pretty good. It brings me back again and again and again. What else can I say? It's like a less intense version of Chipotle (which I also love, but they are so different I go to both places all of the time).
Review Source:This isn't really Mexican food, so don't expect that. It's Americanized tacos, burritos, etc., given names that are references to Seinfeld. I take it for what it is and enjoy it. After all, they've got a salsa bar!
I also appreciate that Moe's doesn't pack cilantro into everything (unlike some similar quickie taco joints).
The food is really good, especially for a chain. You can go with more traditional type tacos or mix it up with any condiment or garnish they have available. A full lunch will probably cost $1 or $2 more than at a "real" taco joint. The service is pretty ho-hum and they kinda give the impression you are distracting them from their break.
By itself the food is probably 5 stars. The fact it is a chain, is as cozy as a fast food place, costs a little too much, and has below average service only brings it down one star.
Though the location is very annoying, I will go there again and often due to its proximity, but my heart is always with Ricky's Taqueria in Elkhart.
