This is a cozy little restaurant at Calle Manzanillo No.81, Colonia Roma Sur, between Calle Aguascalientes y Calle Tlaxcala. It's open from 13 to 20 hours.
The menu is mostly about beef. The churrasco is recommended. Salads are good, and there's a reasonably priced selection of wines.
Desserts are skippable, with the possible exception of the ate con queso fresco.
