Interesting discussion about brunch. In contrast to the reports here, the
only thing I expect when I see a brunch menu is higher prices!
I can see both sides of #2. The other side is that a restaurant that doesn't include "normal" items can lose the business of a group when one person can't find anything to eat. Just as a seafood restaurant will include one non-seafood item for someone who is allergic, it makes good business sense for an "eclectic" restaurant to include one "safe" dish for the less-adventurous eater of the party.
My own pet peeve (which seems to get worse as I get older

) is restaurants that are so dark that I can't read the menu. I try to remember to bring a mini flash light when I go out, but sometimes I forget. (Come to think about it, that's age-related, too!)
