O Thanasis is the most famous souvlaki restaurant in Athens, operating on Monastiraki Square for over fifty years and drawing a constant stream of locals and visitors who consider it a mandatory stop on any visit to the Greek capital. The restaurant built its reputation on charcoal-grilled kebabs — kalamaki — made from a proprietary blend of minced beef and pork seasoned with herbs and onion, served wrapped in thick, toasted pita bread with tomatoes, onion, and a lick of tzatziki. The souvlaki, made from cubes of marinated pork on a skewer, is equally revered among regulars. The kitchen runs at speed: the grill is always lit, the pita always warm, and the throughput of Monastiraki Square foot traffic keeps the ingredients cycling at maximum freshness. The outdoor tables directly face the square and the historic Tzistarakis Mosque, offering one of the most vivid examples of urban Athens watching possible in the city. The mixed grill plate, which brings together kebab, souvlaki, and chips on a single platter, is the go-to order for first-time visitors who want to assess the kitchen's full range at one sitting. Service is rapid and unpretentious; this is not a place for lingering courses but for the precise, straightforward pleasure of excellent grilled meat in a charged urban setting. The restaurant operates until the early hours of the morning, making it a reliable option after an evening at the nearby nightlife venues of Psirri and Monastiraki.

Tips for visiting

  • Order the kebab in pita rather than on a plate — the pita wrapping concentrates the flavours and is the definitive format
  • Arrive at off-peak hours (before noon or after 3 PM on weekdays) to avoid the longest queues
  • The outdoor tables face the square but are exposed to summer heat — sit inside in mid-afternoon if weather is extreme
  • Wash down the kebab with a cold Mythos or Alfa beer from the drinks menu rather than a soft drink
  • The mixed grill plate is better value per gram than ordering individual items separately

Accessibility

The restaurant is on street level with no steps. The outdoor seating on Monastiraki Square is on a pedestrianised paved area that is accessible to wheelchairs. Indoor seating is also step-free. The nearest Metro station (Monastiraki) is directly adjacent.
