Misc. Observations -
The fish taco (yes, that's $4.75 for ONE fish taco!) is classic Baja-style. I currently don't know of anyone who does it better (much better than Taylor's Refresher) so I would return for this dish.
The quesadilla with cheese, epazote & chiles is made from masa, not a tortilla which I appreciated.
The carnitas was moist and flavorful but not outstanding enough to warrant the price.
The guacamole was fresh but bland and was a very small serving for $4.5.
The jicama, grapefruite & avocado salad was refreshing.
The queso fundido was good but not exceptional.
There are three squeeze bottles of hot sauce on each table - ick!!! - the were all bland and oddly sweet.
Yes, you have to wait for the tortillas at Las Mesas, but they are much better than at Mijita.
I will go back to try the sopa de albondigas and the carne asada. Since I work nearby I may go back occasionally, but the taco truck at Folsom & Spear is a lot cheaper; most of their items are just as good and better spiced.
The Mijita staff were wearing shirts that have a skeleton in a chefs hat, stirring a pot. Very cool.
