The last time I ordered a super veggie burrito at Taqueria Cancun (the one at 19th and Mission) I was sorely disappointed. The tortilla was dry and flavorless, there were very few beans, and the avocado was nearly non-existent (abundant avocados being one of my primary attractions to Cancun). This was about two months ago.
Kara had a similar experience last week. Last year I was getting consistently satisfying burritos there - fresh tortillas, lots of avocados, even melted cheese inside the burritos.
Should I just not bother anymore?
On a happier note, Papalote is definitely not a one off. We've gotten burritos there three times now, and each time I am very happy with the beans, and especially the salsa. They put fun things in the veggie burrito, like carrots and potatoes, to make it more satisfying. I've had the shrimp and prawn burritos, and I don't love them, but I think I'm just not a big fan of this burrito filling. The salsa and tortillas make up for it.
Nate ordered the super tacos, and were they ever super! Absolutely enormous (each order comes with two) and the carne asada was very tasty.
Cancun RIP (the walk to Papalote happens to be more pleasant/less noisy as well).
