For places like Mache Bistro in Bar Harbor or On The Marsh in Kennebunkport..do we need to "dress better". Does my husband need to bring a pair of dockers for the trip? I've heard someone say that all Maine is casual but I don't want to walk in with shorts where it might be "frowned upon" Also, the Bite Into Maine truck..I know its in Ft Williams Park but how big is this park. And is this truck something that we will immediately see or do we have to go into the park. Any landmarks near it? Thanks guys.
