How about the I'klectik Arts Lab in SE1 (next to Archbishop's Park) - Ronnie's is not an improvised music club, but the Iklectik puts on loads of great improvised music, almost every night, with some big names (Marshall Allen, Evan Parker, Maggie Nicols etc.) in a beautiful location and at prices that Ronnie's last charged about 40 years ago. It's brand new and not legendary, which makes it much more interesting.
