Investors are interested because GrubWithUs is the only company solving the overcapacity problems that cripple many urban restaurants. Rents are high, so extra space is expensive, but everyone wants to go out on Friday and Saturday nights so the restaurant tries to accommodate them. Leaving a bunch of unused floor space on Monday, Tuesday, and Wednesday. GrubWithUs lets the restaurant sell off that extra floor space in chunks, and keeps a good chunk of the value captured (and also gets people to meet each other, or something like that).
