Once many years ago, I witnessed a proposal in a restaurant. At the time, I thought it was the most romantic way to pop the question, but as I grew older, my opinion changed. I would personally rather have that moment in my life be a private one, and as it turns out, restaurateurs feel the same way. In February's Gourmet [1], waiters, maitre d’s, chefs, and owners all agree that surprising a women with a hidden ring in her dessert or asking for her hand in the center of the restaurant is just a bad idea all around.

According to the article, a surprising number of proposals are turned down, while others have the potential to end up disastrous (choking on the ring or not finding it at all). I guess if it's thoroughly thought out, and he knows she'll say yes, a dinner date proposal could be nice, but where do you stand? Are you into proposals at restaurants?
