KOBE BRYANT drowned his sorrows at Delilah's (100 Spring Garden) Monday night, after his hometown loss to the Sixers. The newly single, Lower Merion-raised Lakers superstar dropped by the gentleman's club about 1 a.m. Tuesday with a few friends and was joined a little later by teammate Andrew Bynum, who had just dined at Del Frisco's (15th & Chestnut).
