On our last day in Seoul we stopped by a Japanese restaurant we’d been passing for days whenever we left our hostel. It’s name in Korean is:오니기리와이규동 with “Handmade Rice Ball & Beef Over Rice” next to it, so I’m unsure if that’s the name or a description of the restaurant or both. I ordered their sanuki udon (사누끼우동) which was good, simple, and filling. Their entire menu is in Korean so it’s best to have a translation app handy. It’s a small restaurant with limited seating but it was a good place for lunch.
