My husband and I live in downtown Palo Alto and have several excellent restaurants at our feet, but we regularly make the trek to downtown San Mateo to eat at Pancho Villa's Taqueria! I love the informal altmosphere, especially since my uniform on the weekend is an Old Navy hoodie and flip-flops - patrons sit on wooden blocks in a maze of modular tables. And the food...wow, it really is exceptional, although the amount of choices can be daunting to a newcomer. I love the quesadilla suizas with asada chicken and hot pico de gallo - se magnifique! My husband goes straight for the aquafrescos, fresh fruit juices in flavors such as pineapple, strawberry, coconut, and orange, which are refreshing, light, and a perfect compliment to the tasty food. Don't overlook the salsa bar, which has several salsa options that range from a simple tomato and cilantro infusion to a complex tomatilla varietal. The salsas are a wonderful addition to an enchilada or a perfect dip for homemade tortilla chips. I highly recommend a trip to Pancho Villa's; maybe I'll see you there!
