The Alcoholic Beverage Control Board has permanently revoked the liquor license of a Southwest nightclub, Abyss, after determining that it posed a threat to the public and club patrons.

The board said there had been a stabbing and a criminal assault with a gun against patrons inside the club, at 1824 Half St. SW, and that more incidents had occurred outside, including a homicide.

The board documented problems from February through July. The club's nightclub license was revoked Oct. 9.

Although the license revocation is permanent, William Bennett, an assistant corporation counsel, said there is still a chance that another nightclub could open at the location. But if Abyss's owner were to reapply for a license, "that entity will not get a license," Bennett said.

In all, ABC documents listed four dangerous events that occurred in or outside Abyss: a homicide; a stabbing; a fistfight, during which a D.C. police officer was assaulted; and an assault with a pistol.

In other matters that recently came before the board, cooperative agreements for six different Northwest establishments were approved by ABC officials. They are designed to address neighborhood noise, the kind of entertainment allowed, security, indoor and outdoor seating capacity and liquor law enforcement.

Grille 88, 1910 18th St.; Whisper, 2477 18th St.; MCCXXIII, 1223 Connecticut Ave.; Larry's Lounge and Coffee House, 1840 18th St.; Fino Restaurant, 3033 M St.; and Lazio, 3263 M St., agreed to various terms negotiated with community organizations, neighborhood residents, Advisory Neighborhood Commissions (ANC), or all these groups.

Fino and Lazio agreed to host no more than 99 and 199 patrons, respectively. They promised to function as legitimate restaurants, with food service as their main priority.

Both establishments are permitted to stay open from 11 a.m. to midnight Sunday through Thursday. Fino's Friday and Saturday hours are 11 a.m. to 2 a.m., while Lazio operates 11 a.m. to 1:30 a.m. those same days.

Both are prohibited from offering facilities for dancing. They have agreed to strictly enforce underage drinking laws and not to circulate promotional materials in public space or on college campuses.

Lazio is prohibited from charging admission fees but may still impose a two-drink minimum.

MCCXXIII was allowed to expand to its third floor and open a new bar, restrooms and seating, limited to 600 patrons.

Sunrise, 911 F St. NW, got the board's approval to expand to its third floor, seating no more than 800 people. Bistrot Lepic, 1736 Wisconsin Ave. NW, was also cleared to expand to its second floor.

The agreements place restrictions on the playing of music at Grille 88, Whisper, Fino and Lazio.

Grille 88 may feature piano playing from 7 to 10 p.m. Monday through Thursday, 8 to 11:30 p.m. Friday and Saturday, and noon to 3 p.m. Sunday. Whisper is forbidden from playing any audio device that the outside public can hear.

Fino and Lazio can have live or recorded music while patrons dine. During the time when music is being played, both restaurants must keep their front windows closed.

In other action, the board approved a license for a new restaurant, Cooperfields, 888 17th St. NW.
