Ganbanyoku & Okonomiyaki

Yesterday, I went to Ganbanyoku with my colleague after working.
Ganbanyoku is a new style of bath using warm stone without using hot water.
Ganbanyoku gave us moist and comfortable sweat similar to water.
After going Ganbanyoku, we ate Okonomiyaki.
My Thai friend has not eaten Okonomiyaki.
We use the cap of pan, when Okonomiyaki is made in this resturant.
It was very delicious. We had very happy time.
