Among the tacky glow-in-the-dark temples, you’ll find plenty of stylish souvenirs at Monastiraki flea market: Look out for amber worry beads, leather sandals and backgammon sets. The central food market on nearby Athinas Street is a smorgasbord for all the senses. Pick up pungent spices at Bahar (31 Evripidou St.) and spicy sausages at Karamanlidika (1 Socratous St.), a welcoming spot to sample cheese and charcuterie. Late-night revelers hit the rough-and-ready 24-hour restaurants inside the meat market for steaming tripe soup.
