2 slices of pizza and soda for $9.99. Or swap the soda for a beer for $10.99. It was a nice place to grab something to scarf down quick as I strolled through Paris to see the sights.
Nothing particularly special about the pizza- it's actually on the greasier side (the grease will definitely help if you're going to do some major drinking later on in the night).
Cute little tables you can sit at to enjoy your food as you watch the passersby.
The only major con was that there was only one lady and one little counter. She was trying to take multiple orders simultaneously, but I'm not sure that really helped her save any time.
