So, this afternoon a group, spearheaded by VI, but joined by Gwiv, myself and three others (appolgies for not getting everyone's handles before posting this), met to taste the three La Pasiditia's.
Well, I'm sure everyone else will chime in as well, but here are my first thoughts.
Of the three LP's, the first one we went to on the east side of the street was head and shoulders above the other two (where I didn't even finish my tacos they were that bad).
Personally, I think the best place we went to was our last stop, a little grocery store/taqueria a block south of Division, Carniceria Y Taqueria Laura at 1051 N. Ashland Ave. (773.384.4567) where the tacos were, IMHO, the best we had. In part it very likely is that they were so much better than the second and third LP, and that they were served with a side of lime, which always helps. :)
Specifically however, they also offered a very nice selection and range of tacos with a flavorful red salsa to accompany them. The grocery and especially the butcher had a very nice selection of food and meats at quite reasonable prices.
I also tried a pumpkin candy which was very tasty (if a bit sweet) and bought myself a coconut water to enjoy later.
All in all an enjoyable lunch, if a bit disappointing with the smells and flavors from the second and third LP. Both had odd odors in the air (never a good start to a meal) and the tacos were greasy, the meat not quite fully cooked, and the flavors ranging from mild to in a couple of cases off entirely.
