We had our Christmas dinner at Tajimaya, it really allowed us to taste really great Japanese beef (the type where they have fused the meat and fat portions). We ordered 2 Christmas dinner (not realizing that each portion of the special Christmas menu was priced differently). So we had a really big dinner which cost us almost JPY 70000 (USD 700) for 4 adults and 3 children. However, there are no comparison to the beef we have tasted, The service was very good, although our experience may be much easier if you speak Japanese. Despite the little shock when receiving our bill due to our misunderstanding that there was only 1 price for the set, we all look very favourably back at our experience even a week later. Was one of the highlight of our trip. Just a note that the seating is very small, and we had a car that takes us there so we not sure about the routes but it has quite a few different restaurant across Osaka
