This is definitely a good place to walk through when trying to beat the heat outside.
It's located by the Planet Hollywood hotel and has various shops in there that are well known and obscure. There comes a point while walking through it that becomes a circle and shoots you back on your merry way through the rest of the stores.
They do have food stalls and locations amongst the shops and there was this cool part of the stretch of shops were a rainstorm would happen for a few minutes.
I also bought some products from their Lush store after wanting to give it a try and got some friendly service there. Actually did another review just for my experience there, but overall a nice place to get some more steps in from the heat.
