The story behind the trailer

From a broken leg to the best corn dog in the Alps.

A Polish-Swiss story about accidental invention, stubborn craftsmanship, and a small blue trailer under the waterfalls.

How it started

Beata broke her leg skiing.

Beata — Betty — Zdunczyk grew up in Poland and settled in Switzerland years ago. One winter she broke her leg skiing in the Swiss Alps and was stuck at home for weeks with nothing to do but cook.

One day she stumbled on Korean corn dogs online. She tried them, loved the idea, then made them her own way: Swiss raclette, Gruyère AOP, locally smoked sausage — and a batter recipe she refined until it was hers.

So she bought a trailer, parked it in the valley with 72 waterfalls, and started selling. That was May 2023. Three seasons later, people travel from across Switzerland, the USA, Korea, Spain and beyond specifically to eat here.

No shortcuts

Why we do it the hard way.

There are easier ways to run a food trailer. We don't take any of them.

Scratch-made. Every day.

Batter mixed fresh each morning. Corn dogs assembled and fried to order. Kimchi fermented in-house. No semi-finished products, no frozen anything — the daily prep is so extensive the trailer physically can't stay open longer than our hours.

Real ingredients, never fillers

Real Swiss raclette. Gruyère AOP. Locally smoked pork sausage. Premium sauces from Roleski in Poland, rotated seasonally. We don't cut costs by cutting quality. Ever.

400+ reviews. Zero bought.

Every review is from a real customer who chose to write it. We don't ask, we don't incentivize, we don't run "review for a free side" promotions. Word of mouth built this place.

Family-run, in person

Betty and her husband ran the trailer entirely by themselves for three years. The recent surge in popularity meant we've welcomed our first new team members — but Betty or Michał is always at the trailer, and you're still ordering from the family that cares most whether you enjoy your food.

It's an experience

Choose your filling, watch the cheese pull, take the photo, eat under a 300-metre waterfall. A 15-minute experience in one of the most beautiful valleys in the world. The corn dog is just the excuse.

"In three years of running the trailer, we have never eaten a corn dog we wouldn't serve." — Betty

Come taste why they return.

Some customers come back year after year. Some travel 6,700 km by caravan. Some wait a full year between Switzerland visits just to taste it again.
