Japan is said to have about 30,000 to 35,000 ramen shops, and about 20,000 to 25,000 udon and soba restaurants, all priced around 600 – 1,200JPY. There are many kinds of Soba and Udon restaurants from cheap stand-up-eating shops to high end, Kaiseki-style restaurants listed on Michelin.
Ramen too comes in all kinds of flavors, pork bone, soy sauce, miso, salt, hot water, vegetarian etc., you will certainly never get bored eating noodles. Noodles are quick and, above all, wallet-friendly! A popular noodle store may have a 1-2-hour line-up, but at least you can always get something to eat, unlike restaurants that won’t let you in without a reservation.
