I was in Tecate on Cinco de Mayo, and during the three hours I was wandering around, hanging out in the plaza, and eating I don't think I saw another gringo. Unlike every other border town I've been in, you can walk the four blocks from the border to the plaza and feel like you are 100% in Mexico. I love the place. I love it even more now that I've had the tacos de harina de carne asada at Los Amigos (on the corner one block south of the southeast corner of the plaza). These things came in delicious fresh burrito-sized flour tortillas with splendidly chewy carne asada and guacamole inside. Add some of the onions, carrots, and jalapenos en escabeche and salsa brought to the table and you're in heaven. Definitely worth the hour drive from San Diego.
