On a busy lunchtime visit last week, Peter Orfanos, general manager for 54 years, noted the new entry area, better to accommodate customers waiting for tables and takeout orders. The dining room expansion on the south wall, into what was a former florist’s shop, stands complete with set tables and flat screen televisions, but is behind velvet ropes awaiting city approval — in 30 days, Orfanos hopes. The private dining room and the back balcony, where construction workers are buzzing saws, will open in a week or so, he added.
