This place is okay. It's fairly expensive, particularly on special nights such as New Year's Eve, where men can pay up to 8000 yen just to get it. There are a lot of very young people here, but it's also probably the most international club in Roppongi. It also happens to be one of the biggest as far as casual dance clubs go. One really good aspect about Lex is that you can leave and go club bouncing, but still come back and go in again because you get a special stamp on your hand. Drinks are really overpriced (1000 yen) once you run out of the free drink coins you get at the entrance, but you can always leave and go drink somewhere else and then come back. Overall, it's worth a visit.
