Samples included tacos filled with skirt steak and chorizo; portobello with grilled corn and cotija cheese; duck leg with crispy skin; and smoky pork belly with pineapple and pickled jalapeno. Other passed hors d'oeuvres included a Campeche-style shrimp cocktail served with black oyster, and mini crab and shrimp empanadas. The bites ranged from good to very good, with the duck tacos being a standout.

As the crowd thinned, the pace picked up, and Albisu and his team kept the food moving until the event’s 10 p.m. conclusion. “We sent out about 1,400 tacos,” the chef told me this morning. “What we expected to serve all night, we did in the first hour.”

Last night’s menu was not only a preview of what will greet diners when Taco Bamba opens in Falls Church later this fall, but what Albisu will serve at his weekly Black Jack appearances through December 17.

The a la carte dinners (walk-ins only, from 6 to 11 p.m.) will feature full-size versions of appetizers and traditional tacos — in addition to the more involved creations Albisu previewed last night — with the menu changing weekly. “This is an opportunity to tweak and get the recipes the way I want them,” Albisu said.
