The City that Only Mostly Sleeps: BU students will soon be able to get tacos until 3 a.m.

The Boston Licensing Board today unanimously approved a request from El Jefe's Taqueria to remain open until 3 a.m. at its outlet on Commonwealth Avenue near the Agganis Arena.

The board noted concerns from Boston University and Boston Police about barflies spilling down Comm. Ave., but said El Jefe's owner John Schall convinced them that is not his market, that he expects to be serving BU students and third-shift workers in need of cheap yet nutritious food.

Although BU Police Chief Kelly Nee said tacos until 3 a.m. would change the character of the neighborhood, and that there are no other places in the area open that late, there are two Domino's focused on BU students that offer pizza until 3 a.m., via delivery. In fact, BU promotes them.

The BU-area taco place will join El Jefe's Northeastern-area outlet in remaining open until 3 a.m. Another outlet at Emerson is open until 2; one serving Harvard, across the river, is open until 4.

Also approved today: Delivery service for between 11 p.m. and 3 a.m. Thursday through Saturday for Turkish Lazuri Cafe, 487 Cambridge St. in Allston, which says the later delivery hours would let it serve a demand for food from local Harvard, BU, BC and Suffolk students.
