Luxe Tajimaya, which we visited back in 2009, opened a little counter inside the JR Osaka Ekimarche.
We recently tried their kurogewagyu sushi. Sweet and salty thin pieces of kurogewagyu (black hair Japanese beef), thick omelette, cucumber, a little lettuce.
Tajimaya Grill : UPDATE 12/2013 the shop is no longer here
