Nai Soie Beef Noodle

Nai Soie Beef Noodle on Phra Athit Road—five minutes from Khao San and a short stroll from Phra Sumen Fort—does one thing and does it right: deep, anise-scented beef broth with brisket, tendon, and springy beef balls over your choice of noodles. Bowls land around 70–100 THB; go “mixed” if you’re hungry. It’s no-frills Bangkok: stainless tables, fans, fast service. Office workers, riverfront regulars, and backpackers pack in at lunch, so swing by before the rush. Hit the condiment set—chili-vinegar and fried garlic—then roll back to Khao San happy.
