Personally I prefer eating in a diner as I like the atmosphere better. I think it's better in there as in fine dining I have to eat almost prim and proper lol. I'm not saying fine dining restaurants are bad though, I just prefer diners as they seem more casual. How about you? Regardless of if it's expensive or not as you have lots of money in this situation, would you rather eat in a fine dining restaurant or in a small diner?
