Imagine all the ingredients you might find at an Italian market and the various ways they can be put together, and you have an idea of Espresso's huge menu. There are focaccia sandwiches (full or half-size), pizza, hot heroes, and lots of pasta, including homemade ravioli. Although Espresso has a big take-out business and does catering, many Sag Harborites enjoy eating in its tight, self-service quarters.
