I am attending a convention this weekend at Hilton Head and I am responsible for dinner for 10 Sunday night. I have encountered some difficulty as my first 2 choices are closed Sundays (Charlie's L'Etoile Verte and Michael Anthony's). I do have reservations at Redfish. I understand it is rather casual, which is fine , but I am entertaining some CEO types. I would appreciate any input regarding my choice. BTW, we are staying at The Marriott.
