If you are in Krems an der Donau either to visit this lovely city or to change trains, let me give you a good snack tip. Mario's Romanian Brezel (Pretzel) Shop is a perfect place to enjoy some Romanian street food. And why not try the classic pretzel or Brezel or as I know it - 'the Covrig'. These are real Covrigi like you would find in Bucharesti or Braov. I love the poppy seed (mohn) topping. This little store is only minutes from the Krems main train and bus stations and right off of the pedestrian Landstraße. I wish Vienna had a Romanian Covrigi shop!
