I think porkyland in logan is better than la jolla. although not the best, the carnitas is quite good in a greasy fast food kind of way. since you can get the tortillas at local costcos now, the chase is gone and they don't seem as good as before (they were available to the masses).
i like la dona, which is across the street from Guild and on the way to Restaurant Depot. Again, nothing super special, but the food is decent and the prices are reasonable.
I sometimes I put carnitas in a quiche, with some cilantro, onions and some cheese...yummy!
Don't bother with Cuatro Milpas, Yes there are lines outside but that's because the food is cheap and generous. I find it salty and basic. If you seek more authentic Mexican, try El Comal on the 2800 block of Imperial. there is also El salvadoreno across the street from El Comal for Salvadoran food. Cuatro Milpas and Chuey's are real basic greasy spoons. Chuey's food is frozen. Last time I asked for an enchilada with beans inside they couldn't make it because staff said the enchiladas are frozen? How's that for authentic?
I prefer Los Quatros Milpas located down the street. They are only open for lunch, and they make great tortillas.
They are known for the bowl of rice, beans and tamale, or the rice beans and chorizo bowl.
Their hot sauce is very hot, be aware.
They do not offer guacamole.
Their menu is limited, but for this place, less is actually more.
Porkyland is very greasy and too salty. The tamales are decent. For good Carnitas try La Michoacana in the Farmers MArket Building on Imperial and 22nd. All they do is Carnitas and you get your choice of the cut, ribs, buche, leg, whatever you ask for. the beans are great too. You can buy by the pound and take home.
this might be too late but here goes. e.d. is right. porkyland makes good tortillas. their carnitas & carne asada aren't very good. the la jolla location is even worse (still good tortillas though).
if i were in barrio logan i'd go to el porvenir instead. they have excellent tortillas, carnitas, chile relleno. cash only & m-sa (hours seem a little flexible).
