The Conamon Bar Rikyu is a takoyaki specialty shop inside a restaurant in Osaka Castle. Diners sprinkle four sauces and katsuobushi on the basic takoyaki as they like. Water is self-service and free, and containers are available for taking leftover takoyaki home. When the weather is good, camping tables and mats are set out, and the seats are high with no backrests, which is uncomfortable.
