Ah, interesting. Searching the dataset for my local area, this seems to include some restaurants, but omits hotels entirely. That's skewing the numbers downward tremendously.

Which explains why Spearmint Rhino is listed in Birmingham (hint: you might get a surprise popping in that establishment for a quick pint).

So nice interface and all but some data curation will be needed - perhaps on a crowd sourced basis? Click and add comment &c.
