For a couple of years now, Chicago’s hottest restaurants like Alinea and Next, have used a ticketing system. It works like this, to reserve your table, you pay for the tickets weeks or months in advance using a proprietary software. The tickets are non-refundable, and the tip is included.

Yesterday, Nick Kokonas joined us in studio along with Brian Fitzpatrick. Fitzpatrick started Google’s engineering operation in Chicago, and is now working on Tock. Here’s our interview.
