Not sure what prices the other Natalie W is used to, but i found Rio Rico to be very well priced. Average price for a meal is about $7-$9. Not exactly Scottsdale pricing. Food was pretty decent. It is a bit like a glorified taco stand, but emphasis on glorified. You are not going to find ritzy cuisine. All in all, for what it is is, I give it a solid 4 out of 5.
Clean, Friendly, Decent Food. Worth going, I will try it again for sure.
