For a long time, our cafeteria at work didn't serve dinner on Fridays. Most people left early on Friday anyway, so it only made sense.

A few years back, Nathan and I found ourselves without dinner plans one Friday night, so we headed down to Fiesta Del Mar for margaritas and chimichangas. They were good, so we went back the next Friday. And the next. And the next.

After a while, we got antsy about the lack of variety, so we branched out to other Mexican restaurants. Other people heard about the fledgling tradition, and soon we had a full-blown event that drew 8-10 people each week.

At this point, we've hit most of the Mexican restaurants in the Mountain View/Palo Alto/Menlo Park area. If it has margaritas and chimichangas, we've probably been there.

Here's an (incomplete) list of the restaurants we've eaten at so far, as well as a few we hope to visit. Feel free to add any I've forgotten!
