I've written about this place before - though it's probably been two years ago - but I thought I'd give an update.
I went again for lunch today. Very good casual guatemalan food there. First, their empanadas are quite good. They are hand made and fried. Try the chicken. Second, the tacos are excellent - primarily because of the tortillas which are all hand made. These are a little different to mexican tortillas. They are much thicker, but much softer. Hand patted, griddle cooked, and steaming goodness. They had fried pacaya, quite a few other good steam-table offerings as well. I still haven't tried their tamales, but intend to next time.
Now, I think the key is going there early for lunch. You'll battle the crowds of workers coming in, but most are there just for take out. It has only three very small tables. But if you go early, the tortillas and all the food is freshly homemade. I've been there for dinner and the tortillas weren't as fresh. Not sure if that's always the case or not.
The tacos are pretty good. The fillings are tasty enough, I guess (stick with the bistek, which though a little salty, is the tastiest). My chorizo filling wasn't that great. But it didn't matter since the tortillas were so dang good.
This is NOT a fancy place. This place gives dive it's name. But if you are looking for a guatemalan fix, or just some really dang good hand made tortillas, this is your place.
