Sloe Bar, Waterloo, SE1

Formerly the Reef Cafe Bar (and probably a dozen different names before that), this place could be a lot better because the balcony - when open - offers a rather impressive view over the station concourse. The serving area runs almost the whole length of the bar so there would be opportunity to serve a large number of customers quite quickly, if only they staffed it properly... As a Select Service Partner outlet, you get the usual "Would you like a packet of crisps or nuts with that?" nonsense, but if you have a BITE card you can at least get 20% of the price of your drinks (e.g. Pride at £2.80 rather than £3.50). One for thirsty travellers who don't have the time to nip outside to find somewhere better.
