Thank you for everyone who took time to post suggestions. I am finally getting around to typing up some of my memories from the trip.
I arrived on Tuesday around lunch and everything I had on my list in the main square area was closed. I opted for some street food of gorditas and neveria (ice cream). Gorditas were from one of the older ladies selling out of baskets on the corner down from the ice cream. Gorditas were filled with a mild peppers, a little overly salted but actually this was a nice setup for the ice cream. I chose the vendor with the most selection – tried for Pinon and Cajeta, but got Pina instead. Pina was very fruity and fresh. The cajeta was a little overly sweet for my taste.
For breakfast had Corunda and Atole. I chose the lady with the blue tarp, mostly because when I came through earlier the man had been so helpful and let me try both atole so I could pick my favorite. The Corunda was terrific softball sized - stuffed with doble crema and rajas (rich, thick cream and chile strips). Crema will be liberally doused over the whole thing too.
Cha Cha Cha – nice courtyard and friendly waiters. A lot of ex-patriates frequent there, so waiters speak english well if you are tired of struggling with Spanish. Excellent Cornish game hen (sorry I can’t remember much more). Guacamole was fresh tasting but could have been a little spicier for my taste.
El Primer Piso – ate at one of the small tables overlooking the main square. Had a local whitefish with a cream, coriander, and herb sauce. The sauce was great, and the fish was flaky. If you really like fish the sauce may cover up the flavors of the fish a little too much, but I like the fish as a carrier for the sauce and other flavors with the flaky texture. The vegetables were overcooked for my taste.
Santa Clara de Cobre Street Food – took another quick bus. Off the small square I got some pork from a cart, and then tortillas and drink next door where I could sit on the tables, eat and watch. The pork was tender but some soot mixed in was a little unpleasant on a few pieces. Cheap good meal.
