I love this place. It's a must visit whenever I go to Vegas. They have two locations - 1 in Aria and 1 in the Bellagio. The one in Aria is bigger and nicer. It reminds me of something you would see right out of a Dr. Seuss book.
I've tried their chocolate, croissant, desserts, and this awesome spiced chicken panini sandwich. It was sooooo gooooood!!! I can't wait to have it again the next time I return to Vegas! I also need to try their crepes. I've heard great things and saw a lot of people order them.
Be prepared to stand in line during peak hours.
