Like most things at the Bellagio, this place is really really overpriced, except unlike the rest of the Bellagio the customer service here is much lower than it should be. It's a decent coffee shop, with decent bakery case options for quick food, but seriously nothing impressive. They aren't wow'ing anyone with a $10 almond croissant, or $12 side dish of pfarro and veggies.
When it's your only option for a quick meal (like it was for me while I was here for work) then you deal with it, but their attitude and their prices make me roll my eyes hard.
