looks like a demand pricing model in disguise. it is rather creative though.
often times demand outstrips supply during the peak times especially during tourist season. Some restaurants raise prices and gouge the tourists while alienating local residents. Those restaurants generally have difficulty surviving the long offseason. The ones that do survive have a large local following. This model gives the opportunity for local clientele to eat there off peak without inflated pricing.
The real question is whether you can get the tourists into a bidding frenzy or not.
