Visiting for a wedding in September- hook me up with the spots!

I love Mexican, Honduran and Nicaraguan food. And I love it authentic- I speak Spanish so if they don't speak English then no problem whatsoever- hook me up with the best hidden spots inside the grocery stores, etc. I'm coming from the Midwest so looking for some good smoked brisket too. I'm researching on my own but wanted to hear some of your favorites.

So far on my list: Anael's Place, El Taconazo, El Ultimo, and Antojitos Hondureños la Porteña.

In terms of Mexican food, I'm a fiend for quesadillas with corn tortillas- know any spots?

Thanks!
