The lamb barbacoa and the "quesadilla de sesos" (which is not a quesadilla in the tex-mex sense: more like brain tacos with a mix of other stuff) are both legit. Both dishes on the greasy side, fwiw.
Outdoor stand doing five different tacos (pastor, suadero, longaniza, campechano, birria) and they're all great. 5 tiny tacos for 30 pesos. Glorious.
Awesome little hole in the wall that only sells al pastor tacos. Get them con todo (with both red and green sauce) and squeeze some lime in to finish. They're small: you'll want at least two.
The sign says "La Reyna de la Roma" fwiw. Great carnitas & campechano tacos. We also got a crispy-shelled gordita that was excellent.
They have two different types of al pastor taco here: the regular ones, and pastor de arrachera (beef). They also have a big grilled for things like ribs (costilla). All of them are great.
AKA hipster tacos. More creative than your average taqueria, especially on the specials menu (on the back of the regular menu). Lots of wine, garlic, etc. Think ~40 pesos/taco, but totally worth it.
The lechón taco is by far the best of the three taco options on the menu. These are fancy tacos at a sit-down bar/restaurant, so be prepared to pay about double what you'd pay elsewhere.
You order at the deep-fryer, then eat, then pay. The tacos pescado, camarón, and the chile relleno (fried pepper) with marlin are all very good.
Fernando's "Tacos de Mariscos" stall is no more, but there were plenty of great other food stall options. And this is a great place to come if you need ingredients: fruit, veg, and lots of meats.
Killer tostadas and agua frescas (aguas fresca?). The shrimp tostada was our favorite, but the rest are all great too. Tamarindo agua fresca for the win.
A very good shot of espresso, and a few lovely benches out front on which you can enjoy the wifi or just watch the world go by.
