Atlantic City, NJ
I have an odd appreciation for indoor settings that are designed to feel like they're outdoors. This is something I typically found in old malls that have a center court with a skylight, trees, park-style benches and faux roof awning that hangs over the entrances to some of the stores.
The best example that I ever found of what I'm talking about was at Epcot Center. It was in one of the countries; Italy, I think, but it was fifteen years ago so I could be wrong. I remember that it was so realistic that I actually forgot I was inside of a building until my stepmother mentioned it.
This section of Caesar's Palace isn't quite that realistic, but it had the same vibe. It's a restaurant hub surrounded in Roman decor with trees and stone floors that give this area a feel of an outdoor cafe.
