It depends on the gozen set meal if you order special menu, they provide 3 different types of sauces like tartar sauce, radish ponzu dipping and tonkatsu sauce by default. Order normal menu, only radish ponzu dipping and tonkatsu sauce.

tonkatsu sauce mixed with black & White sesame (4.5/5) was quite thick and smooth texture with sour plum sauce but but good for dipping fried food as it is sour and you don't feel oily aftertaste.
