Pueblas tacos is a small 3-restaurant chain in the Pasadena area. There's one on the corner of Lake and Orange Grove, one in Hen's Teeth Square, corner of Los Robles and Woodbury and one on Villa and Allen. I went Sunday to the last one for the al pastor burrito. They offer it with rice and beans inside, but I asked for just meat, onion and cilantro. Good-sized burrito and extremely flavorful. It also had a good dkick to it without any added salsa. I was very happy. They also have very good chips and salsa. I've tried the Menudo before and that's good too. Very friendly people waiting on you. I highly recommend for basic authentic fare.
