As casual, mid-level (does that make sense...and/or sound horrible), dining establishments go I don't mind Chili's (it's certainly better than AppleBee's).
I guess the best way to describe Chili's (or at least separate it from the other places that our similar) is that they put a "Southwest" twist on typical casual dining food.
I hadn't been to Chili's in a LONG time (I live in San Francisco and I couldn't even tell you the closest one to me), but I used to go every now and then when living in AZ, and even think I had been to this one when Riverview first opened.
Part of the reason I'm giving this Chili's 4 stars is because when I was here with my family recently we had excellent, prompt service. Our waiter was extremely friendly, and even gave us to-go cups for our drinks when we left without even asking him to do so. Also, I don't know if this is a new thing at Chili's, but we were given free chips & salsa like you get at a lot of Mexican restaurants (I noticed if you check in on foursquare this offer is made, but I didn't even bring it up).
As far as the food goes I ordered the honey Chipotle chicken tenders w/fries & corn on the cob and it was good. Everyone who I dined with was satisfied w/there meals as well. It doesn't hurt that the food at Chili's is pretty cheap compared to other places that serve similar food.
I know some people hate on places like Chili's because they're so commercial (and I'll admit...I can be one of them), but this place is pretty legit and I'd definitely come back.
