Use the route below for planning, then open the linked sources for details that can change.
Keep the route inside Ullidan Street
KTO's Cheongju itinerary and destination page connect Crash Course in Romance with Ullidan Street and Café Oingt, the operating business used for Nation's Best Banchan. These anchors form one small commercial cluster rather than two distant attractions. That makes the route practical, but it also means the business cannot be treated as a permanent set. Start with the public street, confirm whether the café currently welcomes ordinary customers, and add Cheongju Early Printing Museum or another public cultural stop for non-drama value. Do not label Jungang Park, Yonghwasa Temple, or every shop in the combined KTO itinerary as part of this series.
Walk Ullidan as a living neighborhood street
Ullidan Street links local cafés, restaurants, small shops, and cultural destinations in Cheongju. Use normal public pavements, keep storefronts and residential access open, and avoid photographing identifiable customers or residents without consent. The official source establishes the street cluster, not a promise that every sign or composition remains unchanged. Save the Korean name 운리단길 and the return gateway before setting out. A short walk can continue to the printing museum area without inventing another filming connection. If construction or an event affects the route, use the public museum fallback rather than searching nearby alleys for unverified academy, house, or character addresses.
Enter Café Oingt only as a normal customer
KTO identifies Café Oingt as the shop exterior associated with the drama's banchan business. It is a real business that controls opening, seating, purchases, queues, photography, and use of its logo. Check its current first-party channel before relying on a visit. Do not occupy a table solely for photos, expect the fictional menu, move furniture, or block the entrance for a reenactment. If the café is closed, full, or no longer operating in the same form, keep the Ullidan public walk and cultural attractions. Do not substitute another private shop simply because its façade resembles the series or appears on an old fan map.
Add Cheongju's printing culture as the fallback
Cheongju Early Printing Museum and the Heungdeoksa temple site give the neighborhood an independent reason to visit. They are not presented as Crash Course in Romance filming places, and that distinction should remain explicit. Check the museum's current official notice, then arrange the street and museum in the order that fits arrival and closing conditions. A non-drama anchor protects the day if the café is unavailable and reduces pressure on one small business. Keep meals flexible and choose local shops as ordinary customers rather than repeating a stale fan ranking. End with a confirmed route back to the gateway instead of adding an unrelated Cheongju screen location.
Use the fictional shop only as brief context
A concise mention of Nation's Best Banchan is sufficient to connect the real café with the series. Do not reproduce dialogue, tutoring plot summaries, stills, posters, menus created for production, or a shot-by-shot route. The current street and business may look different because signs, tenants, furniture, and planting change. A reusable photo should show the lawful present-day destination and carry its own license; it is not permission to copy protected broadcast imagery. Keep schools, tutoring academies, houses, and guessed addresses out of the plan. The traveler task is a respectful Cheongju neighborhood visit with a cultural fallback, not a search for private character spaces.
Verify the street relationship and business access separately
Use KTO's combined Cheongju course and Ullidan destination page for the filming evidence. Use Café Oingt's current channel, Cheongju tourism, and the museum operator for live visitor conditions. Recheck business status, customer rules, museum closure, local weather, and the return connection close to travel. Do not recommend static café hours, menu prices, or a guarantee that production signage survives. The Go decision depends on two distinct public visitor points within the official cluster: the public Ullidan street and a legitimate café visit. If the business no longer accepts ordinary customers, the page must be reviewed rather than replacing it with a fan-sourced address.
