Go to Williams seafood. It is to the right just as you are exiting the last bridge to the Island. Other than that I recommend that you spend your free time at Hilton Head or on River Street in Savannah. Tybee is a dump!
Sorry Lex. Williams is long gone. You can still get a whiff of what it was like by going to Paula Dean's brother's restaurant (Uncle Bubba's) but it is nowhere near the same.
Old story on Williams burning. Guess it was '04. WTOC, Savannah, Georgia, news, weather and sports | Arson the Cause of Fire at Williams Seafood
There is another place out there near Tybee called the Crab Shack where I have been once and it was okay. They have a live alligator pit and you can buy dog food that they let you feed to the gators on a pole and string. The Crab Shack "Where The Elite Eat In Their Bare Feet!"
If you like chicken fingers and beer there is still a Spanky's on Tybee.
Lex, when I was a little younger some friends and I used to go to a fish camp on the May River near Bluffton, SC and gig flounder at night. The mullet would jump in and out of the boat. Union Camp owned miles of riverfront property and it really felt like you were in the wilderness although we could boat to Hilton Head in very short time. Really good memories.
kev, I think you need to provide a synopsis of your impressions post visit.
