BRR's fish taco thread reminded me about this one.
I found out I was the most adventurous of our group. Though I revelled in streetmeat and suffered absolutely no ill effects, the other 3 guys would not partake. Even had the shrimp kabobs from the beach vendors (and who knows how long they'd been walking up and down the beach with those.

)
Beef, pork, and fish tacos, cerveche, fruit on a stick, sweet roasted corn on the cob, guacamole, you name it! All of it was fabulous! And I have a newfound appreciation for tequila cocktails.
(Also did the parasailing and zip-line canopy tour.

)
Now, though, I've discovered that I'm ruined for any Mexican restaurant fare back home. I'll have to start looking at cookbooks and try my hand at some more authentic dishes.
