Probably the cheapest thing anywhere near central London. But we really lucked out with our host, Toral the food scientist, cooking instructor, expert, aficionado, etc. When I travel (which is constantly) the thing I enjoy most is local cuisine and drink. When you're a tourist it's easy to make mistakes. Not with Toral. She sent us to Borough Market first and specifically Padella for some of the best fresh pasta I've ever had. All the other food and drink options were great too. I could've stayed all night, which we kind of did. Then she sent us to Maltby market, small but exquisite. I was very much in my happy place. Then we stumbled upon another of her recommendations near Piccadilly Circus, KilnSoho. I couldn't believe how good it was. We ordered at least 8 menu items between the two of us. Her spare bedroom isn't the most spacious, if you're in London to hang out in your apartment pick somewhere else. If you want superb recommendations and advice from someone totally in the know, Toral is awesome.
