The Zoning Board of Appeal on Tuesday approved plans by the owner of Chubbs Taco & Tequila Bar, 750 Adams St. to increase its number of seats and to add live entertainment - with no more than two acoustic instruments at a time - at night.

Chubbs attorney Ryan Spitz said Chubbs' owners, who include Julian Bolger, were able to increase its seating from the 151 seats it got when it took over the location from the Industry through better use of the space, rather than adding more room.

Spitz added that on nights when Chubbs hosts music, it will close any open windows at 9 p.m. He added the music will be all live performances - Chubbs is not going to have any DJs.

Technically, the restaurant needed approval of a conditional permit for takeout from the board - Boston zoning regulations require the board to approve all takeout in the city.
