best bday venue. the guys at 10 william street kindly reserved a table for 10 of us despite a "no reservations" policy.. and all 10 of us were raving about the place after. food was superb, wines were different but tasty, but the highlight was the service. everything was perfect, from our glasses always being topped up, to advice on wines, and service that was attentive but not intrusive. i cannot rave highly enough about the experience we had, particularly as i'm a keen foodie and have eaten at most of sydney's best.
