Down Richmond Highway, just past the big shopping center, there is a wonderful Taqueria called Tacos el Costalilla. I had four tacos and one sope. I had an al pastor, two carnitas and one Carnaza al Vapor. I have never heard of Tacos al Vapor, but it apparently is a style from Jalisco. Carnaza is beef. The people are very nice. The salsas are hot. They have the carrots with serrano chilis that I love. We were in taco heaven. The sopes were fantastic. You can get cabeza, lengua, tripa and buche' tacos, which I never order because I am not that kind of adventurous but it is always a good sign that they are the menu. If a Mexican place has one of the those items on the menu, or birria (which they also had) or rabbit (canejo) it is a sign that they are catering to Mexican and not American tastes. I will definitely be back, especially since the owner said he would make me some machaca. Unfortunately, my Southern Californian idea of machaca is not the same as his. But, if a chef will make you something special, you shouldn't say no.
