Thank you all for your information. @
hccj I was nervous about this which is why I asked. I'm interested in trying their restaurants if I have comps to use, but not so interested that I want to pay real money I could be using to gamble, for other stuff, or at one of the many excellent restaurants in LV. @
Big Mac Yes they don't have a lot of clarity on their website at all about how all this stuff works. Which is kind of why I have piled these up so much. The only time I asked about using them was at the Siegfried and Roy gift shop, because we were buying a couple of souvenirs, and there the answer was no.
I'll just plan on going to Noodles one day for lunch. But I will probably pop by the mlife desk at Bellagio first to double check and see what else I can use them on there.
