They have a cold table, a hot line, and a dessert spread - what I can remember from today -
Cold: guacamole, salsas crudas, one ceviche + one coctele de camaron, huitlacoche stuffed zucchini, nopales salad, marinated mushrooms and marinated chiles - there is more but you get the idea
Hot line: sopa de albondigas, sopes, quesadillas, chilaquiles, caulifolwer coated with egg, green chile quail, red chile braised brisket, carnitas (sometimes they have roast suckling pig but not today), chile rellenos, seafood enchiladas + rice, beans, etc.
Dessert - churros, tres leches, mango cheesecake and a bunch of other tortes - I didn't have dessert so I don't remember these as well
I probably remembered about 60-70 percent of what's out there - pretty nice spread
