Many would argue that Pappasito's is the king of Tex-Mex restaurants in Houston, and it would be hard to argue with them. Consistently tasty, every location seems to always have a crowd. Sizzling fajitas served with their insanely addictive mantequilla dipping sauce is a top draw, followed closely by the array of enchiladas. Possibly due to the festive atmosphere (or that they're just plain good), the tart frozen margaritas seem to go down quicker than normal here.
