Chicken-only ramen is the correct call for Bangkok. A nine-hour tori paitan sits lighter than pork bone after a long night, which is exactly when most people end up here. The Maze Special, dry ramen with soup served separately, is the more interesting order because it shows how the kitchen thinks about texture independent of heat. I would start there.

The entrance is open-air, and the cooking operation sits in a stall near the front. Counter seats face inward; table seats extend the space further back. That layout is straightforward in the way a ramen-ya should be: the food is the point, and there is nothing between you and the kitchen to suggest otherwise.\n\nThe broth is chicken. Only chicken. Simmered for over nine hours until the stock turns opaque and thick, a proper tori paitan that coats a spoon with collagen. The Torisoba Special is the signature order, every element built around the same base. For something structurally different, the Maze Special is a dry ramen: noodles arrive without broth, and the soup comes on the side in a separate vessel, letting you manage temperature and dilution independently. Gyoza come alongside as a natural companion.\n\nKitchen hours run 11AM to 3AM, every day of the week, sixteen hours of continuous service. That four-hour block past midnight is the reason this address shows up on late-night shortlists. The amenities listing confirms alcohol on the menu, which shifts the register after 11PM. Beer is available. Small plates extend the table time.\n\nThis is the 本店, the honten, meaning the original. A second Nanase branch has since opened at Onnut on Sukhumvit 79, and a third at Phrakhanong, confirming the concept scaled beyond one site. Dine-in, takeaway, and delivery are all listed as service modes in the venue data.\n\nOne practical note: the Facebook page at facebook.com/Nanase.Ramen is the primary channel for menu updates and announcements, and the venue has no separate website. Check the page before visiting if you are planning around a specific item or seasonal addition.
