On busy Adrianou, ideal for its view of the Acropolis, Agora, and Temple of Hephaestus (not to mention its excellent people-watching), Dioskouri has been serving tasty mezedes at affordable prices for many years. The place is crowded day and night with lots of locals. Highlights are the seafood dishes and spicy keftedes (meatballs). It only accepts cash. Dioskouri also has a branch at nearby 13 Dioskouron St (210/321-9607) with the same menu and slightly less delicious people-watching.
