It is beautiful, hot, there is a place to drink tea and coffee, have a snack. Buy a souvenir. Tourists are charged a lot, 2 manats if you are a citizen or have a residence permit.
The gas seems to be supplied from the pipe, because natural gas has no smell, and the one that burns in this place clearly has the smell of ODORANT.
I liked the project only for its business model - with its simplicity of implementation, it is very attractive in terms of profitability. If you go this far, you will still pay 10 manats for admission.
