I'm going to an afternoon show in Canary Wharf on Sunday and it'll finish around dinner time. It's a couple of hours home, so I might want to eat afterwards - any recommendations for somewhere that might be quite nice, but that I wouldn't feel like a lemon for getting a table on my own? Not hugely expensive, either. Open to most kinds of food. I could always find a wagamama or pizza express, as I've done both of those alone before, but thought there might be something a bit different that people could recommend.
