Seeing San Diego Mexican restaurants being discussed in another thread, I thought it would be a good breakout topic. I realize that it has been covered before, but it probably is good to bring up from time to time. I also realize given the changes in Old Town, it may be too soon to rate those places, or the relocated places that were moved out of Old Town.
So, if you had to pick a sit-down Mexican restaurant in the San Diego area, which ones do you like, and which do you avoid? I've seen some negative comments on the On The Border restaurants. I've found them OK, but I'm not that discriminating. I've gotten better and worse food at various El Torrito and Acapulco restaurants - both of which seem to be quite dependent on location when it comes to quality.
I've found Cozymel (UTC area) to be a half step above the other chain places, though there have been a few disappointing trips there. I like the margaritas at Su Casa in La Jolla, and have yet to get anything there that turned me off, but nothing foodwise stands out in my mind. Tony's Jacal in Solana Beach is a good place to go for something slightly different (maybe CalMex 70s style food? I don't know - wasn't here then. :-)
