This is the Jean Philippe Patisserie that is in the Aria. It's much bigger than the one in the Bellagio and the line moves pretty fast. They have sandwiches, crepes, panini and many other treats. We always stop at both locations for our morning coffee, but like this one as it has more seating and faster lines.
Both have the most amazing treats. My favorite is the flan. I get it all the time.
