Prague has a reputation for having some of the best spas in the world. Prague is also known for some of the best beers in the world. So, while the Bernard Beer Spa might seem like a crazy idea, it actually makes a lot of sense. If there's anywhere in the world that you'd consider taking a bath in a giant vat of beer, the capital of the Czech Republic is the place to do it.
Looks like a normal bath. Well, a really nice normal bath. This explains why the beer bath treatments begin at around $100.
It's not just a hot beer bath. You'll also get a hot beer massage. That sounds like a euphemism for getting physically kicked out of a bar, but it's not. (At least, not in this scenario.)
After thirty minutes of soaking in the hot water, brewer's yeast, malt, and hops, you'll be feeling better than ever (assuming it even takes THAT long).
