4. FILM CAFE
This place is awash with couples on dates who've just been to the beautifully renovated BFI Southbank and fancy a drink afterwards, as they dissect the art house movie they've seen. So if you're not the romantic sort, or have just been given the boot, you might want to avert your eyes and concentrate on the alcohol. But, whether you're propping up the sophisticated new bar inside or chilling outside at the trestle tables under Waterloo Bridge, it's a buzzy place for a beer and a bit of latesummer people watching.
BFI Southbank, Belvedere Road, SE1 (020 7401 9000). Beer, £3.50; glass of wine, £3.95
