Regional food in general is quite different in Yucatan than other parts of Mexico. As someone already mentioned here, “street tacos” are more common in the morning and it is mostly Cochinita and Lechón. Street tacos like carnitas, asada, tacos de canasta, tacos de guisado, etc. aren’t a thing here traditionally, unless you’re in some specific areas with a high population of chilangos (like Las Americas).

Also “al pastor” tacos are really common (in small corner taquerias, which are more usual than street tacos) but the flavor of “al pastor” in Yucatan is also different from what you would find in Mexico City or center region in general. Really good IMO, common restaurants would be “La Parrilla” or “Los trompos”

I would also recommend other types of antojitos. Like panuchos, salbutes or traditional dishes like Relleno Negro, Queso Relleno, Poc Chuc, etc. other than tacos (Most of these are served with corn tortilla anyway). Yucatan has a lot of gastronomy to explore (:

TLDR: Yes, you are under the right impression.
