As I was getting nowhere trying to make a winterlicious lunch reservation at C5 by phone, I have taken a different route and successfully reserved a table using OpenTable.com. OpenTable's advice is that if you want the Winterlicious menu, you should let the maitre d' know this before you sit down. Has anybody else tried this? I can't see a restaurant making too much fuss but are they legally bound to serve the Winterlicious menu if requested? Does the service become noticeably frosty if you do what I have just done?
