Go to Mellow Mushroom and get the meatballs and a white pizza.
Wet Willie's down on the waterfront, not the one up top.
See the waving girl stature while you are down on the waterfront.
The fountain at Forsyth park.
Colonial Park cemetery is worth walking past.
The Forrest Gump "bench" is on the north side of Chippewah square. No actual bench and never was other than for movie but stand in the middle of the street and take a picture and the background matches so that's the attraction.
Take the trolly tour to save a lot of hot walking.
To be honest, the attraction of Savannah is the architecture, the city layout/squares and grid pattern, and all the shops and restaurants. There are a bunch of art galleries, SCAD is there. You can walk around and have a southern take on city living. Very different vibe than you get in NYC.
