Oude Kaas's chef worked in Holland for 13 years before he decided to bring the flavors of Dutch cooking back to Osaka with him. There's a good selection of beers (German and Belgian mainly) to go with the unusual food. The latter include excellent stamppot (mashed potatoes with whatever vegetables and seasonings are around the kitchen that day) and over 60 pancake variations (combos like cheese, banana, rum raisin and salami).
