Relax at an outdoor table right on the water, under the trees and overlooking Kranae Island. (The island, joined to the mainland by a causeway, is said to have been the refuge of Helen of Troy.) The menu at this restaurant and cocktail bar goes beyond the usual Greek standards: You’ll find chicken burgers, seafood risotto and even mushrooms stuffed with ratatouille and topped by a truffle-infused cheese crust. Order with caution, as Nisaki is known for generous portions.
