If you want to hustle through your huaraches, thick, fried tortillas stuffed with barbecued goat (two for $7.99), forget it. Be prepared to linger over chips still sizzling from the fryer with two kinds of fresh salsa (green tomatillo and tomato) while -- on weekends, anyway -- a roving band of trumpet players and guitarists serenades your table. Kick back with a beer (you don't really need to go back to work, do you?), reset your watch to slow time, and sample from a foodie's dream menu of delicious if challenging meats to pack into your tacos. Roast pork, fried beef tripe, pork stomach, beef tongue, spicy pork sausage, beef head, stuffed green peppers, pork in red pepper sauce, fish, shrimp, and vegetarian fillings are priced from $1.69 for a single soft taco to $6.99 for the fanciest burrito -- to eat with the seven different bottles of hot sauce on every table and your choice of corn or flour tortillas. Heartier appetites will warm to seven kinds of dinner soups (sieta mares is $13.99), chicken in mole ($8.99), roast quail ($10.99), enchiladas ($9.99), chimichangas ($8.99), and fajitas ($10.99). Cactus and eggs ($3.99) and huevos rancheros ($3.99) are served all day from the breakfast menu. Nobody speaks a word of English, so if you're linguistically challenged, break out your high school Spanish or be prepared to grunt and point.
