6 Best Restaurants in Tokyo, Japan

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.

The classic bowl of ramen is topped with slices of pork, but Darumaya, in the fashion district of Omotesando, has a slightly different take, topping its noodles with grilled vegetables. In the summertime be sure to order the hiyashi soba, a bowl of chilled noodles topped with vegetables and ham in a sesame dressing. Another shop specialty is the tsukemen, where the noodles and broth are served in separate bowls. Dip (don't drop) the ramen into the broth. Despite the focus on veggies, vegetarians should note, the soups and sauces are not meat-free.

At Ueno Station is a branch of an amusing ramen chain. Ichiran serves tonkotsu (pork broth) noodles. Rather than sitting at a table and ordering off the menu, you'll choose and pay for your meal and your seat at a machine. You then use the order sheet at your table (it has English on it) and choose how you'd like it served. You'll hand that and your order tickets through a window. Like magic—presto!—the curtain rises and made-to-order steaming bowls appear.

Open from 11 am to 11 pm, this ever-busy ramen joint, now an international chain with almost 30 locations in Tokyo alone, is an ideal quick stop on or after a night out. The classic ramen is the Shiromaru, which features a creamy pork-based stock, thin yet slightly firm noodles, and a topping of chashu pork slices. Other options include the Akamaru, which has a little red miso mixed in the soup, and side dishes such as gyoza dumplings.

Kaijin shows that ramen doesn't have to be rich and heavy to be satisfying. The shop specializes in a clear shio (salt) seafood-based broth that is both light and flavorful. Think of it as a more nuanced version of the soup in Hong Kong style wonton soups. Instead of the traditional slices of pork, Kaijin tops its ramen with freshly made seafood and chicken meatballs. The thin, chewy noodles, made from two kinds of flour, give the ramen just enough body without making it feel heavy. Expect to line up, but once you sit down service is quick and efficient.
