- Read the store policy: many cafes expect one drink per seated customer, but dessert substitutions and child exceptions vary.
- Dine-in usually means reusable tableware: follow the cup and tray system shown by that shop instead of assuming every cafe works alike.
- Seat saving is common, not insured: customers often leave a bag or laptop briefly, but travelers remain responsible for valuables.
Three rules to check before settling in
One drink per person is a common house rule, especially at popular dessert cafes and small venues. It is not a universal national law. Some shops count a dessert toward the minimum; others require every adult to order a beverage. Read the menu notice or ask, “Is one drink per person required?” before ordering.
For dine-in service, reusable mugs, glasses or plastic cups remain a familiar standard. Korea's disposable-product rules and enforcement approach have changed over time, while the government continues campaigns encouraging reusable cups. In practice, use the vessel the cafe assigns and do not move a dine-in cup outside unless staff approves. When finished, carry the tray, cup and dishes to the marked return station (반납대) unless table service is clearly provided.
Seat saving and Korea's trust culture
In many Korean cafes, customers place a bag, coat or laptop on a table before ordering. Visitors may find this relaxed seat-saving custom surprising. It reflects ordinary local behavior, not a guarantee against theft or damage. Keep passports, wallets and phones with you, avoid occupying a seat before confirming that it is available, and never move another customer's belongings. In a crowded cafe, order promptly rather than guarding a table while companions remain in a long outside queue.
Laptop, Wi-Fi and charging etiquette
Cafe workers and students who stay with laptops are often called cagongjok. Laptop use is welcomed in many large cafes, but a small shop may display No Study Zone, time-limit or no-outlet rules. Check signs before opening equipment. The Wi-Fi name and password may appear on the receipt, menu board or counter; ask staff rather than testing private networks.
- During a long two-to-three-hour stay, buy another item when appropriate and release large tables needed by groups.
- Use headphones, silence calls and keep charging cables away from walkways.
- Do not unplug cafe equipment or occupy several outlets with adapters.
- At peak time, accept a posted seating limit and clear the table promptly.
