Simco's, 1509 Blue Hill Ave. in Mattapan Square, goes before the Boston Licensing Board on Wednesday for permission to extend its closing time from 1 a.m. to 3 a.m.

The venerable hot-dog stand, which years ago had later hours, got a one-day suspension last fall when a police lieutenant found it open at 1:45 a.m. one August night.

The board's hearings start at 10 a.m. in its eighth-floor hearing room in City Hall.
