I am staying at the Hyatt at DFW airport for two nights and was wondering if there a recommended eatery that a foodie like me could easily visit with a reasonable cab ride (less than $50). It doesn't necessarily need to be expensive, just unique. I also would like a tip on good authentic Mexican especially tamales. I am from Michigan and the mexican food sucks. I am looking for authentic mexican, not tex-mex. Unfortunately I am not that familiar with the Dallas area. Thanks in advance.
