This Japanese import, whose first shop was opened in Akita Prefecture before spawning numerous offshoots, has been a local hit since day one. The first stateside location, it is set in a Clairemont strip mall and yet attracts a crowd; two more recent spin-offs, in Mira Mesa and Hillcrest, are similarly popular. Inside, one may expect efficient service and a no-frills vibe.On the menu, ramen is the main attraction. Diners are faced with few choices: the house broth is a rich, porky tonkotsu enhanced with miso; while the tantanmen is a unique take on Sichuan dan dan noodles, bolstered with ground pork and a touch of spice. Each item comes with excellent springy noodles and the option of add-ons—the ajitama egg, for instance, was a strong contender.
