Neighbors of the Montrose Collection Restaurant and Banquet Hall testified against the facility in a license revocation hearing Wednesday before the city zoning administrator.
Glendale Neighborhood Services is proceeding against the establishment, charging it is operating full time as a banquet hall.
The restaurant, at 2832-33 Honolulu, is owned by Armen Alvazian and Levon Migtroyen. It has been operating since last April, on the site where the BRIC Montrose formerly was located.
Neighborhood Services inspector Rene Sada said he has visited the site numerous times during his investigation, and never found restaurant customers there. Under its permit, the restaurant can only use 30 percent of its space for banquets, and must be open for walk-in service.
