Trześniewski is a Viennese bistro, founded in 1902 by the polish gourmand Franciszek Trześniewski.
Speciality oft the house are the famous rye bread sandwiches with egg-based spreads.
Try it! Along with it you should order the smallest beer in town (0.2 liter), the so called “Pfiff”!
Fun fact: Everyday Trześniewski process 600 kg of rye bread and 1000 kg of spread!
So every year they sell 4.5 million sandwiches, therefor they use 1.1 million eggs!
