I arranged a lunch here for my husband's 40th birthday. I can not fault the food nor the young gentleman serving. However I was left red faced as we overheard a couple next to us being offered chocolate for a birthday treat. They said it wasn't their birthday. I waited for them to realise their error but we never received them. I also caught the maitre'd looking us up and down and he was also frosty to me and another guest at check out. Shame on you sir.
