Tacos los Parados in Roma Norte (Baja California y Monterey):
Tacos Pastor de Arrachera It's a little taco (and etc.) bar. Some D.F. native told me they were the best tacos in the city. Order at the counter, get your tacos, dress 'em at the bar, at eat there standing up.
For those who have the sweet tooth for horchata, there's is good.
Pechuga (chicken breast) tacos
Even the hamburguesas were really good in a primal way. Their default toppings were ketchup, mustard, lettuce, tomatoes, raw onions and jalapenos. And you can add more to all your shit at the salsa bar!
I love anywhere with a salsa bar!! Everything is nice and hot.
