Looking for cheap lunch spots near the LA Convention Center. Staying at the JW Marriott, but prefer not to eat at LA Live. I read that there are excellent spots on Pico, but I am female and will be walking alone, so I would want to stay safe. Are there any taco trucks nearby? I know you can take public transportation to Chinatown and stuff, but it would be great if I can just walk somewhere. Ethnic eats are a plus. Thanks!
