I've been there three times. Once, on a date and the other two with friends. Frankly, it's great for both :)
I tried their London Fog, but it wasn't all too great. There was way too much vanilla and not enough milk - but maybe it was just me. I'm not a fan of coffee, so I won't comment on that (however I've heard great things about their free-trade stuff!) HOWEVER... THEIR MILKSHAKES ARE THE BOMB.
THEIR MILKSHAKES
ARE THE BOMB. I think I'm the only person who orders them too, haha. Banana's the best out of the three (Chocolate, Strawberry &Banana).
The venue is cute, however it's hard to find a spot when you're with friends. Very retro.
