I am going to Houston next week to visit my sister and will be staying in Spring (she lives in The Woodlands). She recently moved and is unfamiliar with restaurants in the area. I am not opposed to driving into Houston for this treat as I live in Seattle and there is no Tex-Mex to speak of up north. I don't care if its a hole in the wall place...just want to have a satisfying meal. Any suggestions would be most appreciated.
