Decent little gift shop at the Bellagio that also serves as a mini convenience store. This location sits right at the entrance of the elevates for the main tower.
Well organized and good selection of last minute "forgot at home's" They're open 24 hours which is nice.
I wish they had a better selection of ready to eat mini meals (Lunchables for example), but they did have some jerky and other similar dried protein.
They tend to be busy at night with people buying drinks or late night snacks. Charging to your room seems to be a longer transaction because they have to look you up and that slows things down. Remember to show them your mLife card for your discount. They don't always ask if you have one.
