I had lunch at Taqueria Santa Rita today. Kenny from Rogers Park's view of the tacos al pastor is on target. The chips arrived warm with 2 salsas. The salsa cruda was very light on the chiles while the cooked salsa was only moderately hot. There is a small parking lot. They stay open to midnight on weekdays and 2 am on weekends.
On my way back east on Lawrence, I was stopped by a man at a new restaurant: The King of Burritos Taqueria and Steak House (2739 W. Lawrence). He said they do not serve pork and was wearing what looked like a yarmulke with Mexican embroidery. From the menu he gave me, it is definitely not Kosher because they use cheese and sour cream with meat. I wonder what lamb barbacoa tacos or tortas tastes like. That will have to wait for another day.
Los Pinos got much more sprucing up than a new awning. I can't recall the former name on the place or find the current name in the telephone book under any of several variations, so I suspect there is new management. The old place was an uninviting dump.
You might want to loosen your geographic limits to include Lawrence and Montrose west to Kedzie. The Mexican places I have been to on Montrose have not been outstanding but better than the Taco Loco that used to be on Lincoln north of Foster. I haven't been too eager to inflict the other location on my stomach, so my information may be outdated.
Of the several small Mexican restaurants on Lawrence between 3000 and 3200 west, I had a good lunch at Huaraches. They have DF-style tortas among other things. A few weeks I had the torta al pastor, which was a slightly crisper and a little oilier than at Santa Rita.
