Champaign chipotle serves decent food but it has two strikes against it.
1. The line for this restaurant borders on the absurd. I've seen times where the line wraps around the restaurant then out the door. I've even seen people lining up before the restaurant has even opened. If you like waiting in long lines to eat passable mexican food then this is the place for you.
2. The portions tend to be on the skimpy side. I've been to chipotles across the country, and I have noticed that this one gives the smallest portions. It doesn't really matter for the management because the demand they have is abusrd, but it us upsetting. Chipotle isnt cheap for that they provide.
If you have time, I'd recommend going to Maize instead. You still have to wait in an crazy line, but the food will actually be worth the wait and walk.
