I finally got to eat today at the Hamburguesas al Carbón at the intersection of Calles Colima and Morelia. That is just to the west of the Jardin Pushkin.
(By the way, I didn't discover this place, but read about it in various books, such as Lonely Planet Mexico and the recent book by Nick ....
It's small, it's very busy with a clientele that slices across the social strata; it's sizzling, the burgers are good, starting at $22 pesos for una sencilla and going up to about $27 with doble queso y piña.
I need to check the menu board more closely.
No fries, no shakes, no desserts, no seats. There are bottled soft drinks.
It's open about 10 a.m. to 10 p.m.
As an exemplar hamburguesa Mexicana, the swiftly grilled patty is more the vehicle for lettuce, tomato and a load of condiments than a thick, juicy patty. They cook them with a little pink remaining inside. I preferred it without the ketchup but definitely with the sliced, pickled jalapeño slices. The grilled pineapple ring is not in my usual hamburger vocabulary, but in the interests of testing, I tried one. It made a sweet, juicy contrast.
I confess: I ate two. First one a sencilla con queso y todo. The second una sencilla pura pero con piña.
Oh..the buns are also briefly grilled, sometimes leaving grill marks on the bun top or bottom. I found that visually exciting.
(For those of you who might be concerned about my bonafides as a Mexican food aficionado, :-) , I went a while ago to Pozolería Tizka. You can hardly get more authentic than that place.
By the way, at about 2:30 p.m., the neighboring barbacoa de carnero and the tacos or tortas stands closeby the hamburger stand by were doing a fraction of the business of the Hamburguesas place. You can form your own conclusions.)
