Notice the house rules
Check the café’s ordering and outside-food policies. Some places require an order per person; others set different rules. Ask the staff when a sign is unclear.
Start with one useful sentence
“여기서 주문하면 돼요?” means “Can I order here?” A short, polite question is often enough to begin.
Enjoy the pause
Tipping is not customary in Korea. Follow the venue’s payment and service instructions, and give yourself time to enjoy where you are.
