Everyone raved and raved about the Fremont Street Experience as something I must do while in Vegas. So I went, I saw, and I don't ever need to go back.
It's my understanding the casinos here are less pricey than on the newer section of the strip, but there was just too much going on here for me. It was full on sensory overload between all the crazy outfits of people trying to make a quick buck, the zipline overhead and people milling about like they had never been in a public place before... it's just not my scene.
I can surely appreciate it for what it is, but I would not go back in any hurry.
Also, if you are looking for the heart-attack grill, I can completely understand why this is it's home.
