When we ordered dessert at the California Grill, they added something extra to it:
You could always call the restaurant to speak with a manager & request that they put the Happy Anniversary chocolate card on the dessert you order. The dessert in the picture above is the warm valrhona chocolate cake.
When we had dinner at Citricos, I had pre-ordered my favorite dessert from Victoria & Albert's: the passion fruit mousse in an orange scented chocolate purse. This dessert is HEAVENLY. I had actually requested it on our V&A's dinner night, but for some reason, the request wasn't given to the chef, so he found out when we had reservations at Citricos & sent it over there on that night. If you are looking for a special dessert, this is one in a million
Good luck!
