The Penthouse at Mastro's

Accommodating guests across private dining rooms and The Garden, the venue centers on celebratory steakhouse dining, pairing cuts of ribeye and bone marrow with sides like lobster mashed potatoes. Diners frequently mark anniversaries and milestone birthdays against a backdrop of fine wine and performances from a live violinist, though the lively room means the atmosphere can tilt from intimate to boisterous when large groups take over neighboring tables.
