Unfortunately, I couldn't taste the best Mexican food ever in San Diego--Tacos El Gordo--because I'm a pescatarian and the only meat choices they have are beef and I think pork. But thankfully, I wasn't really hungry that time. Not sure why, but I just wasn't. The guys just ate their food, trying out new taco choices they could get--beef liver, beef brain...etc.
Apparently it was really good. I would never know.
