Flower vases that look like urine bottles lying on a counter at Crazy Toilet Cafe in central Moscow, Russia.

The new cafe, opened last Friday, has a toilet-themed interior.

Food is served on crockery designed to look like small bathtubs and urinals, and cocktails are served in mini urinals.

Instead of chairs, there are about 50 real toilet bowls for guests to sit on. But if guests need to use the toilet for real, there are three cubicles at the back of the restaurant.

The restaurant's Crazy Lunch menu costs 500 roubles (about S$11) and features three dubious courses, each with a lavatorial theme: a brown and creamy mushroom soup served in a toilet bowl, followed by a swirled sausage served with three piles of steaming mashed potato.

If visitors have not lost their appetite by this point, they can finish off the meal with a bowl of whipped chocolate ice cream.
