There are a ton of places in Redwood City and right near by that look good, but I've only really sampled El Grullense on El Camino at Jefferson since it's close to my house and next to my favorite video store. Some of their items are hit or miss, but I love carnitas, and theirs are great. Their beans are also very tasty, but the aquas frescas are a little bit syrupy for me, though, and I haven't been as impressed with their carne asada. So... where else is good? Anyone want to try a taco crawl sometime?
