October 4 is National Taco Day! Tacos are a SoCal staple -- locals brag about ours being the best this side of the border, and visitors can't get enough. Los Angeles Mexican food is also incredibly versatile, and if you've lived here long enough you'll have seen both good and bad in upscale restaurants, hole in the wall places, and roving trucks. L.A. is home to inventive fusion (kimchi tacos, anyone?) and tried and true classics (al pastor made on a trompo), and there are so many options that something delicious is probably right around the corner. These are some of our favorites, what are yours?
