"I broke my leg skiing in the Swiss Alps. During recovery I accidentally invented the best corn dog in the world. Now I sell them from a trailer under a waterfall."

The story behind the trailer
It started with a skiing accident. Beata — Betty — broke her leg in the Swiss Alps and spent weeks at home with nothing to do but cook. One day she stumbled on Korean corn dogs. She tried them, loved the idea, then made them her own way: Swiss raclette where there was generic cheese, locally smoked sausage where there was a bland hot dog, Gruyere because why not.
The result was something nobody else was making — not in Lauterbrunnen, not in the Jungfrau region, arguably not in all of Switzerland. So she bought a trailer, parked it in the valley with 72 waterfalls, and started selling.
Everything is made from scratch. Every single day. No semi-finished products, no shortcuts. The batter is prepared fresh, the kimchi is fermented in-house — Korean mothers who've tried it say it's excellent — and each corn dog is assembled and fried to order. The daily prep is so extensive that the trailer simply can't stay open longer. It's the price of doing things properly in a small kitchen.
Three years in, people travel from across Switzerland and beyond specifically to eat here. Some come back season after season. In three years of running the trailer, Betty and her family have never eaten a corn dog anywhere else. They didn't need to.

What people say
"Traveled 6700km by caravan and believe me when I say this — by far the best corn dog. I'll do it again."
"I live in Switzerland and this is the best thing I have ever eaten in my life. It's been 1 week since I went and I'm still dreaming about it."
"Our favorite thing we ate in Switzerland. Seriously out of this world. Mozzarella with panko and garlic mayo."
"I would go to Lauterbrunnen just for this again. The best corn dog I had in my life."
"We ate here every day. The only day we didn't is the one day they were closed. Definitely our favourite place to eat in Lauterbrunnen. We recommend this be your first stop."
"I waited a year to come back and eat it again. It did not disappoint."
"By far the best we've ever had. We tried the Bunsik chain in London — they don't compare."
"Raclette cheese absolutely stunning. Full of flavour, perfect cheese pull. Whisky BBQ sauce was a 10/10. Amazing view of the waterfall."
"The most unique corn dog experience I've ever had in my life. An experience for everyone of all ages."
"For sure a must-have every time I come back to Lauterbrunnen. Don't eat anywhere else."

"A must visit. Incredible food, service and scenery. Don't miss this stop while in Lauterbrunnen."
Good to know
A Korean corn dog is very different from the classic American version. It has a thick, doughy rice-flour batter and is rolled in crunchy toppings — panko breadcrumbs, cubed potato fries, or Flamin' Hot Cheetos — before frying. The result is crispier, chewier, and much more satisfying. The cheese filling stretches dramatically when you pull it apart — that cheese pull moment is basically designed to be filmed.
We use genuinely local Swiss ingredients — raclette cheese, Gruyere, and regionally sourced smoked sausage. Nobody else in the Jungfrau region (and very few places in Switzerland) makes Korean corn dogs. Add nine sauces, three coatings, and a view of the Swiss Alps, and it's a different experience entirely.
Yes. Swiss Taste (100% raclette) and Cheese Pull (100% mozzarella) are both fully vegetarian. All three Zapiekanka variants are also vegetarian. That's five vegetarian items on the menu.
Zapiekanka is Poland's most beloved street food — a long baguette half baked with melted cheese and mushrooms, finished with sauces. Our Seoul version adds homemade kimchi. Crispy, gooey, vegetarian, and unlike anything else you'll find in Switzerland.
Yes — every single day, without exception. No semi-finished products, no shortcuts. The batter is prepared fresh each morning, corn dogs are assembled and fried to order, and even the kimchi is fermented in-house. Korean mothers who've tried our kimchi say it's excellent — that's the highest compliment we could ask for. The daily prep is so extensive that it's one of the reasons we can't stay open longer than 11:30–18:30.
Monday to Thursday and Saturday to Sunday, 11:30–18:30. Closed on Fridays. Season runs May through October.
Important: everything is made from scratch every single day — the prep is so extensive that we simply can't stay open longer. We sometimes sell out before closing time. Always check Google Maps or our Instagram @bettys_corndogs before making the trip.
Yes, card payments accepted. Cash also welcome.
We're a food trailer without formal seating. But Lauterbrunnen has benches, walls, and one of the most spectacular valley views in Switzerland. Most people find a sunny spot and make it work. The waterfall backdrop makes every photo worth it.
All our products currently contain gluten. Please speak to our team on-site about specific allergens — we're happy to help.
No — corn dogs are best eaten fresh and hot, 30 seconds after they come out of the fryer. Come find us in person. It's worth the trip.
Absolutely. The train from Interlaken Ost to Lauterbrunnen takes 20 minutes and runs frequently. Many visitors come to Lauterbrunnen specifically for the corn dogs — some travel from Zurich, others from across Switzerland, some from much further. The combination of food this good with a view of the Swiss Alps and Staubbach Falls makes it a very easy decision.
We're about 7 minutes walk from Lauterbrunnen train station and roughly 5 minutes from Staubbach Falls. We're right on the main road through the village — you'll see the blue trailer. Most people stop at Betty's before or after the waterfall walk, or between hikes.
Yes — one of our most popular crowds. Kids love the customisation (choosing their own coating and sauces), and there's something for everyone including vegetarian options and the Sweet Doggy dessert corn dog. No formal seating, but the village has plenty of spots to sit down and enjoy the food together.
We serve customers in Polish, English, German and Spanish. You'll feel at home whatever language you order in.
We're open from mid-April through the end of October. That covers the full spring, summer and autumn tourist season in Lauterbrunnen — including the busy months of May, June, July, August, September and October. Always check Google Maps for current status before visiting, especially early and late in the season.
Betty's Corn Dogs. Rated 4.9 on Google across 400+ reviews, it's one of the top-rated food experiences in the entire Jungfrau region — and completely one of a kind. These are not standard Korean corn dogs. Betty developed her own original recipes from scratch, using Swiss raclette, locally smoked sausage and Gruyere — ingredients you won't find in any corn dog recipe anywhere else in the world. The result is something entirely unique: a fusion that exists only here, in a small blue trailer under the Swiss Alps. People travel from across Switzerland and from other countries specifically to eat here. The raclette corn dog with panko and garlic mayo is the place to start. Add homemade kimchi on the side — made in-house, approved by Korean mothers.
During peak summer months — July and August especially — there can be a short queue, particularly around lunchtime. Each corn dog is made fresh to order: typical wait is 5–6 minutes, and even during the busiest moments the maximum wait per order is around 10 minutes. We sometimes sell out before closing time. Check Google Maps or Instagram @bettys_corndogs on the day to confirm we're still open.
