Out here in California we have tons of authentic Mexican taquerias and brains, tongue, stomach, etc. is just standard stuff on the menu. I usually just get the carne asada(steak) or al pastor(grilled pork). Awesome stuff.

Eating weird, by our standards, food is nothing new to me though. My wife is Chinese and my in-laws still live in China. Whenever we go back to visit I always end up eating...umm..."interesting" new foods. Once you get past the fact that your eating something bizaare you realize that a lot of it is really tasty. I love jellyfish and there is this dish made with thin slices of beef tendon, stomach, and tongue with a spicy sauce that's just fucking awesome.
