Beppu - Hell Steamed Food

Will be visiting Beppu for first time in October and have a query about Jigokumushi (hell steamed food).

I understand there is a steam cooking centre (touristy) near Umi Jigoku, but are there any restaurants in town that do such cooking ? I tried searching using Tabelog but couldn’t find anything meaningful since it doesn’t fall into any washoku genre.

It is a dish steamed with the steam of Jigoku (hell,hot spring), so it probably doesn't exist in the town.
I ate puddings steamed in Kannawa.
