We ate at Los Arbolitos on Tuesday. We were their first customer (and only customer) at least til 9pm when we left.
The Margaritas were excellent (bartender is ex Si Senor).
The menu includes the Mexican standards, but additionally has a range of steaks and other items.
The owner, Marisa, was for many years at Panorama. -A very personable lady.
Our waiter Eduardo you might recognize from Las Palomas.
I think having a successful restaurant in this location definitely helps the vibe in the neighborhood, I hope they make it.
