One of the better suburban Mexican restaurants is out in Chanhassen. Rey Azteca is a popular Mexican restaurant serving a wide variety of authentic traditional Mexican and Tex-Mex chow. The service was not that warm - but they get the job done.
The Mariachi band on Sunday evening is a pleasant entertaining surprise. Food not special, but pretty good and priced to move. Packed on the Sunday evening we were there. Good place to feed a family.
