Ideas for a fun restaurant/venue for my DD's 18th Birthday Party in London

[figgypie]

My DD turns 18 in October and she doesn't want a big party (thank goodness after the one she had for her 16th!). She just wants to go out to London with about 6 friends for a fun night but I am very out of touch of cool venues! Has anyone got any ideas for somewhere fun and lively for a group of teenagers. Maybe with live music or entertainment or??
Thank you

Maybe an actual gig of whatever musician she likes preceded by dinner in a restaurant local to the venue?

Not a night out, but the afternoon tea bus tour is fun - B Bakery

Little Nan's?

The ice bar is cool-pun intended

what about a show? You can get dinner and show packages and then a nearby bar.

Crazy Coqs at Brasserie Zedel by Piccadilly Circus?

A really nice place is Circolo Popolare in Fitzrovia. Or Gloria in Shoreditch. Run by the same people but good food and very pretty surroundings.
