Afuri
Ramen is the quintessential Japanese fast food: thick Chinese noodles in a bowl of savory broth topped with sliced grilled chashu (pork loin). Each neighborhood in Tokyo has its favorite, and in Ebisu the hands-down favorite is Afuri. Using the picture menu, choose your ramen by inserting coins into a ticket machine, find a seat, and hand over your ticket to the cooks, who prepare your ramen then and there. There's limited seating, and at lunch and dinner, a line of customers extends down the street, but as expected, the ramen is worth it. The signature ramen here is yuzu shio (citron and salt), but there are other options, including a vegan ramen.
