Petit "O" is the lobby bar quietly running under Spago at St. Regis Istanbul. Where Spago plays for the rooftop crowd, Petit "O" leans into the St. Regis house tradition: a rotating signature Bloody Mary specific to each city. Istanbul's is the Misty Mary — turnip juice, red basil, rakı, and dry ice for the Bosphorus fog effect. International wine list and aged champagnes run alongside a classics-first cocktail program. Quiet, formal, and easy to get into — the antidote to Spago's reservation theatre.
