Nanba Udon is an old neighborhood restaurant in the shopping street next to Namba Station, serving udon and soba. It offers meat udon, curry udon, and yubu udon, all in a broth with katsuobushi aroma. You order by buying a meal ticket from a kiosk and handing it to the staff, and the food comes out within 3 to 5 minutes. The tempura toppings are fried in advance, so they are soggy and chewy.
