Izushi-soba is served on small plates and you can try to eat them as many as you want. One portion is served with five small plates. They are served with dipping sauce made by dashi (Japanese soup stock made from fish and kelp) and a choice of spices to add in the sauce. It is said in Izushi that if you are able to finish the plates and lay them up as high as the length of a chopstick, then you have eaten like a grown up man.
Izushi-soba is served with raw egg, tororo(grated yam), chopped scallion, daikon oroshi (grated Japanese white radish), Wasabi (Japanese horseradish)
Each shop make efforts in making their original dashi sauce with fine quality stocks.
Izushi is known for its rich dark dashi made with bonito flakes and dried kelp.
