Has anyone tried using the "Complimentary Chef's Taste" perk? I tried twice...
Saltbox (San Diego): I mentioned that I'd like to use it to our server, who had never heard of it (awkward!). Then I brought it up on my phone and he brought us some dessert, which was nice. He was pleasant throughout the exchange, but I hate the drawn out conversation of "can i have free stuff? no really, it says here that i get free stuff!".

Scala's Bistro (San Francisco): Hoping to avoid any potential awkwardness, I mentioned the perk in the "additional notes" part of my opentable reservation. Our waiter brought us a delicious tomato soup as a result, though he mentioned that they don't really do the perk anymore. It'd be nice to see some clarification about where and when (I know recently they clarified that it's dinner-only) the perk applies.
