Ya, this place is older, but I found better deals here than the "Premium" outlet place downtown.
This is located a few miles South of Mandalay Bay on LVB. I boarded the deuce bus in front of Bellagio and rode it to the outlet center, then back again.
There's a decent selection of stores here, and the food court options aren't bad either. The place was packed on the afternoon I visited.
I will certainly find my way back here again.
