Bruce Willis partied so hearty at a BevHills Japanese restaurant that he had to come back the next night and apologize! Bruce and his entourage blew into the quiet neighborhood eatery for sushi and spirits, guzzling beer and wine and putting away enough raw fish to fill a trawler’s hold — all the while rollicking loudly and disturbing the other diners. The following evening a repentant Bruce — who’s a regular at trendy Sushi-Ko — returned and said “so sorry” to the staff . . . then made amends by forking over HUGE tips to everyone!
