Okay . Besides the terrible after smell when you finish dining , it is a great and value buffet meal . 3132 yen for 2 hours of all you can eat mutton and pumpkin . What more can you ask ? Draft beer for 570 yen .

there is 2 type restaurant in this park.
ordinary and first class.
I recommend first class type.
I have ever been both ,so difference is so clear.
not so different price

Interesting museum. Enjoyed the tasting set of beer very much. Great food at the restaurant - had the Genghis Khan lamb which was very delicious and reasonably priced. Highly recommended.

In terms of food, it was definitely worth the price as the lamb was pretty delicious and it's only 2900Yen ($29) for an all you can eat set. On the other hand, the environment was not the best for eating. The inside of this restaurant is unbelievably smoky and noisy. It was so noisy, I couldn't hear what my girlfriend is saying when she's sitting right in front of me.

This place was highly recommended by the locals for the barbeque lamb and beer. Unfortunately, we booked the indoor restaurant which was packed, noisy, smoky and uncomfortably hot.
We ordered ala carte and the food was good but the environment was unbearable.
Strongly recommended to book the outdoor open air restaurant in summer.
