Is it fair to pick a photo for a garnish? Yes, when it's something like mustard ice cream on the gambas maize cake at Playa. The whole dish sounds interesting - mojito-poached shrimp, braised napa cabbage and those little ice cream pellets - and looks gorgeous. Chef and owner John Sedlar Tweets that it's cool and spicy for a hot summer day. We'll take his word for it. And take two, thanks.
