A small room with a tight fit around the perimeter is the first floor. The second one was more restaurant-like, but I just looked in there, it was occupied for a private gathering. Downstairs there is a clean bar, the museum was probably named out of habit. This is the second establishment under the Prague Beer Museum brand - the second is located on Mira Square.
You can take 0.15 ml each to taste before ordering the full size. And you can try sets of 5 varieties - I did so. A set of dark and a set of ale, and that's it. You eat goulash in bread and ask for a gastronomic refuge in this bar for the rest of your life. It's a very nice place.
The beer is delicious, in principle, the choice is sufficient, BUT the price tag is not the cheapest. Simply, nothing distracts from your favorite drink).
