I've kind of been a Masa hater for years, though I probably revisit annually anyway because it's in my neighborhood. But Dax claimed the $1 tapas menu was worth checking out, so we finally gave that a try.
This does indeed turn out to be a tasty bargain. We really liked the guajillo-rubbed steak with guac, grilled chorizo, BBQ chicken skewer, crispy calamari, smoked chicken taquito, pork empanada, and tuna ceviche taco. The eggplant dip was the only one we wouldn't order more of. We didn't try the mussels or shrimp ceviche. 12 or 13 of these made for a very pleasant, filling, varied, and very reasonable meal for two.
You must specify that you want to order from the tapas menu, and they seat you in the bar. The deal goes all night Su-Th, and after 9:30 Fr-Sa. We will definitely return for this.
