Eating “somewhere fancy” on the UES usually means eating somewhere that looks a hundred years old with people whose ties look awfully tight, but Sant Ambroeus’s UES location is an exception. You’ll see a younger, trendier crowd here drinking freddo cappuccinos under the gorgeous art deco chandelier. You come here for the pastries—don’t leave without trying the Principessa cake—but their pastas and pretty salads are very good too.
