Hilton Head Food/Drink Recommendations

Family trip to Hilton Head later this summer. Not expecting to have the best quality food given what I have seen posted and just the general touristy atmosphere. Want a few recommendations for waterfront dining and just food in general (20-30 minute drive to Bluffton or somewhere is not out of the question)

No small children though so any cool bar/restaurant type places would also be appreciated.

Thanks for the help!
