The karashibi spicy miso ramen here has a cult following — and for good reason. You choose your level of kara (spice) and shibi (a strange, tingly mouth-numbing sensation from Japanese sansho pepper). First-timers should go futsu-futsu (regular for both); the brave can attempt oni (devil) level. The broth is rich, the noodles are chewy, and the numbing sensation on your lips is unlike anything you've experienced. Look for the black door curtains.
