solveig will be less busy than guetta.
if you don't mind spending the money, a night at lío might be something for you. have dinner there (very expensive, be warned, but at least it's also good), watch the show and then have a dance afterwards. alternatively only get there for about 1am and then only go for a bit of party. you'll have to pay to get in though if you only come for the party and this is one of the places where you definitely have to dress up a bit - smart casual.
Checked Lio on Youtube and yes Lio is our scene, aired, good looking people, sophisticated...thats one of the type of clubs im looking for...would enjoy the cabaret show but probably way over my budget...whats the fee only for dancing do you know? What is the best day to go?
