It's not as famous (or cheap) as its nearby rival Aska, but take the hint: the 99% Japanese clientele should tell you something. The fiery Kara Misso Lamen (spicy broth and spiced pork in addition to the usual condiments; R$42), doused with the house-made chili sauce, is a revelation; as is everything on the menu. Veg options as well. Get slurpin!
