Meyhane & Seafood Editor

Can’s approach focuses on the way a table unfolds over time. Seasonality of fish, freshness of meze, service pace, sound level and billing clarity are all treated as parts of one experience.

Areas of focus

  • Meyhane culture
  • Fish and seafood
  • Meze
  • Bosphorus restaurants

Editorial principles

  • Ask about seasonality and the day’s catch
  • Include the table’s rhythm in the review
  • Check pricing clarity
