I was just telling my husband (who used to order food for his startup every single day) about you guys and he pointed out that your website really doesn't make it clear you're in the Bay Area, or whereabouts you serve. The yelp page is a lot clearer, but you might want to put a little more location information on your site; the 323 phone number confuses things too.

Good luck! You could try the free samples approach at the Hacker Dojo one lunchtime, perhaps? see if you can get a regular set of customers there.
