Summarized from Korean traveler blogs. Mention counts reflect how often a complaint appeared.

What's disappointing

The portions may be a little small for men.

What's still okay

Right next to the station ticket gate, basically a 0-minute walk, so it’s very easy to get to.
Almost no train noise, so you can eat in peace.
Both the course meal and udon feel carefully prepared, with attention to the ingredients and presentation.
The food is beautiful and makes good use of seasonal ingredients, so there’s plenty to enjoy visually.
The dishes came out quickly after ordering, and same-day reservations were sometimes possible.

💡 If you still go

Lunch ranges from udon and rice bowls to course meals, and reviews mention both walking in without a reservation and finding reservations useful. The course meal is meant to be enjoyed slowly, so leave yourself plenty of time.
