I don't know about Loot -- not sure yet whether they'll prove to be a good fit for Zihua. Feels like they're pushing an envelope that doesn't want to be pushed.
As for Angustina, haven't seen it yet, and look forward to trying it. (Might be fun to get some unsuspecting friends/relatives to try the chalupitas de chapulín...and then, afterwards, explaining what they just ate.)

LOOT is entering it's fourth year and seems to be fitting in just fine with a younger crowd of locals and tourists with money. And local residents who like the coffee.
Angustina is in it's third year also and ditto.Good mezcal and really interesting food. Surely you have seen it, right next to Chuletos along the paseo.
