Tickets to Restaurants

Chicago chef Grant Achatz's next restaurant, called Next Restaurant, will sell tickets for seatings. As the NY Times reports:

Anyone wishing to eat at Next after its scheduled opening in the fall will pay in advance on its Web site. Like airlines, Next will offer cheaper tickets for off-peak hours. A table at 9:30 on a Tuesday night, say, would cost less than one for Saturday at 8. Ticket prices will also vary based on the menu, but will run from $45 to $75 for a five- or six-course meal, according to the site, nextrestaurant.com. (Wine and beverage pairings, bought with the ticket, will begin at $25.)

Two questions:

1. How will they respond to scalping?
2. When will they move to auctions to set the price?
