Looking into Nightlife in London for a week on Sunday. Will be in the city and looking to party. We are in our early 20s and looking to checkout the hip trendys bars and clubs. Dont know where is cool to go to on a Sunday night so thought i would try here. We are staying in Knightsbridge at the Sheraton park tower then going to Cactus Blue(if any one knows it) on fulham road for dinner. We dont know where to go as we are not from the city and would like to go to a busy trendy club where all the cool london jet set people hang out...im trying to give my girlfriend a really top night out and she likes to party.
