I sincerely recommend this place! The staff was extremely kind and helpful.
The beef, prepared by chef Kurumi, was perfectly cooked (matching my taste); it was melting like butter in my mouth. She also gave me a couple tips on how to enjoy even more the meat (e.g eating it with lettuce and another sauce).
The side dishes were also very tasteful.
If I'll visit again Osaka, I'll return to this restaurant, for sure!
Nice touch, the Origami present given at the end :)
