Each season, Top Chef's elimination challenges often have the chefs cooking for crowds of folks at this or that food festival, water park, restaurant wars. To be distinguished from when they cater a wedding and that is clearly not open to the public at large.
How do people know about these events before the show airs? Is it invite only? Does the show post about events beforehand? Do you need to sign up for alerts? This season was in Seattle, and I would have loooved to attend something.
