3.5*
Zaza is one of the better Yorkville cafes you can stumble into. I prefer visits during the summer, where if you're lucky enough to grab one of the three tables out front, you can enjoy a fine evening of people watching.
The espresso is indeed good here and even better when made into an affogato (they have a pretty decent selection of gelato).
Overall a pretty simple, down to earth coffee shop amongst the razzle dazzle of Yorkville. Simple is good!
