Near T1 departures, Lotteria is the fast-food you already know
Right in Incheon T1, Lotteria is the local answer to McDonald’s, with burgers, fries, fried chicken, and shrimp burgers on the board. Prices sit in typical Korean fast-food range: expect roughly ₩5,000–₩8,000 for a burger and closer to ₩9,000–₩11,000 for set meals with fries and a drink. It’s fully post-security in Terminal 1, so you’re not gambling with immigration lines before food.
Menu basics stay familiar: bulgogi burger, cheeseburger, fried chicken pieces, and the classic shrimp burger you see at branches in central Seoul. Portions track with city stores, not airport “supersize,” so a single set around ₩10,000 usually works for one person. Soft drinks, basic coffee, and sometimes seasonal items (think limited-time burgers) rotate through, all clearly priced on overhead boards in won.
Service runs quick during peak bank times for Korean Air and Asiana in T1, but lines around big departure waves (for example 10:00–12:00 and 22:00–00:00) can stack up to 10–15 minutes. Food then comes out in another 5–10 minutes, so budget 20–25 minutes total if you hit a rush. Earlier mornings and mid-afternoons between bank waves are noticeably quieter and closer to walk-up-and-order.
Compared with other T1 options that push ₩15,000–₩20,000 for a sit-down meal, Lotteria keeps costs lower, especially if you just grab a burger-only order under ₩7,000. If you’re hungry and short on cash before a long-haul out of Incheon T1, this is one of the cheaper hot-food stops after security and before boarding.
Tip: check the overhead departure screens near the T1 Lotteria before you queue; if your flight from Terminal 1 starts boarding in under 25 minutes, skip the combo set and order something small you can eat at the gate instead.
