I'm actually a very laid-back, relaxed person. I don't care how people dress on the street, in stores, or even most restaurants. But when the people sitting at the table next to you are dressed sloppily, it made our celebration seem a little less special, like just an every day occasion. I'm not judging the people at all, but I think it's up to the restaurant whether or not they want to create a certain atmosphere. I won't name the restaurant here, and I certainly would go back in the future, but I'm unlikely to consider it for a special celebration. To be totally honest, my favorite type of restaurant is one where I can get Michelin-star quality food in a very casual atmosphere. In those situations, I'm totally comfortable in jeans and collar-less shirt. This, IMO, was not one of those restaurants.
