Udon - Gourmet in Osaka

Udon is a thick noodle made from wheat flour. It is served with fish stock, soy sauce and a sugar base soup. There are many varieties of toppings such as Tempura, egg, beef, wakame (seaweed), curry etc. In Osaka, Kitsune udon, which is served with sweetened deep-fried thin tofu, is popular. Sanuki (Kagawa pref) udon restaurants are popular in Osaka too. Sanuki udon's noodles are firmer and chewy and there is less soup than Osaka udon style.
