I'm a New Englander but lived in LA for many years, so I like to think I know good Mexican. I'll be in Dallas for five days starting Wednesday. I'm looking for recommendations of the best Mexican (aka interior Mexico, not Tex-Mex, no queso please!) restaurants in the area.
My tastes run to hole-in-the-wall, family owned, small places, nothing fancy. Although I'm mainly looking for lunch-dinner recs, I'd also love to hear about places that serve breakfast and do it well.
I'll actually be staying in Richardson (unfortunately but it's where we're required to stay for my son's hockey tournament), but I am willing to drive.
Thanks in advance for any and all suggestions.
