I tried the Salt rooms once, although not the ones you're talking about. My wife is a fan of them and packs the kids there whenever one gets sick.So today, we went to that Crystal place near pacific fair shopping centre.... did the salt room therapy ....I think it helped with clearing my stuffy sinus a bit!
When I do some looking around their store afterwards, I see these books...cooking on salt blocks. Himalayan salt blocks.
How weird is that!
Anyone tried it?
In Romania they have salt caves, where you can go and spend the day. There are all sorts of activities to keep you occupied ranging from table tennis, golf, snooker, bowling, boats to paddle around a lake (in the cave), kids playground and even a bar to grab a drink. Apparently doctors over there often tell patients with respiratory or skin conditions to go spend a day at the caves.
