The bathrooms are kind of far from seating area and you have to show tickets like 3 times to get to your seat, so it takes a good 10 min to visit the restroom, from the seats. The prices are ridiculous indeed, with one kind of beer reaching $16, but this is pretty common across all venues (at least they have good selection).
There is a large area outside the seating/stage area, with all kinds of huts offering food, drinks, and merchandise. We parked literally one row closer and waited the same amount of time to get out.
Not knowing this beforehand, we bought premiere parking for $40, which was a colossal waste. Parking was free and pretty easy to get in and find a great spot. Attended a Rammstein show this last weekend.
