I heard ~AQUA~ threw a nice party in honor of restaurant director Jean-Claude Persais, who has left the floor at Aqua after 14-plus years of service. He wants to spend more time with his family, who is based in LA. He is starting his own consulting company and will continue to act as a consultant for Aqua; he also remains a partner at Café de la Presse, so you will still see him around. Aqua's general manager Karim Guedouard will continue to oversee the restaurant (he has been there since 2005). 252 California St. at Battery, 415-956-9662.
