BFI IMAX Southbank.
Aside from being the biggest screen in the country, its one of few true IMAX screens.
Only trouble you will find is that it can be tricky getting tickets around big releases, especially at prime times. Its also worth going for the premium seats as they are in the optimal viewing position.

Might be the south bank one not sure been a while since I've been
How do you book seats? I've just spent 10mins googling around, and can find nothing like a simple method of booking?
Yes, that is the BFI Southbank (Waterloo) you are describing.
Odeon were granted to run the booking system and operation of the cinema for BFI last summer. You can book it through Odeon like any other film, just choose it from the drop down list.
