22 Avenue O, Brooklyn NY (see comment 1 for photos as photos)
In the ethnic heterogeneity of Avenue O, beside a Chinese pizza shop and an Uzbek Sephardi eatery, is a quaint Mexican and Guatemalan venue, that has some of the most superb Mexican food on the planet, outside of Mexico, El Barrio and 4th Ave. It is about a block away from the Albanian bar, and two doors down from the very nice ladies in the Russian small grocer with the good meats and cheeses, and the sweet cat.
Of course the first thing that one should do is stay clear away from the burrito.
Second, talk to the woman who is basically the manager or hostess. She will point you in the proper direction.
I chose the Taco Dorados, at 9 dollars a plate. I forgot to state what filling I desired, and by the time I came to do such, she had stated "they are already filled...with chicken...." I did not protest.
When the plate came, the chicken was mingled very nicely with cheese. As these are deep fried, or almost deep fried, the mixure of the chicken and the cheese was quite consistent.
I asked early for Habanero chili sauce, and she stated that they did not have any. They had a prominent Guatemalan brand that is always nice, and they also had a homemade hot sauce.
She warned me that the homemade was very hot. This is the best sign.
It was splendid.
Most authentic places of Mexican in NYC area have really hot home made sauce.
Chavela's in Brooklyn is quite the rave, but places like these, by the dozens in Brooklyn are far better.
