Do as the Greeks do, and finish off a long day at the beach (or a visit to the Marathon Tomb and Museum) by heading to a traditional beachfront taverna to enjoy the sunset and regional cuisine. Isidora's front tables are nearly immersed in the sea, and the rest of this eatery is bordered by a Mediterranean garden. Proud family matriarch Isidora is behind the relaxed atmosphere and the delicious homemade dishes. Head into the kitchen to have a look at the fresh fish of the day, and choose some sea bream, which the chef will grill especially for you. It all begins with rich seasonal salads and fresh village bread and ends with either a halvah dessert or a plate of fresh fruit that's on the house. Just remember: it's cash only.
