Finally I decided to try it out.
The taco sample plate at $6.50 offers 6 mini tacos and is the best deal. All the tacos are very different and you can taste the care that went into finding the perfect blend of spices with the meats, down to the black beans and fresh made corn tortillas.
The owner of Guisados is related to the carniceria next door, so they get fresh corn masa, grounded and mixed, fresh every 30 min.
I also tried a tamale de mole. The mole sat on top of the tamale but was very tasty. Reminded me of how my mom made hers.
Overall it is very tasty and homemade-ish. Give it a try.
I don't know if they will survive on just outsiders and the occasional local that wants to spend that much on a taco, but we'll see.
