Premium Street Food — St. Gallen
Best Smashburger in Town
Selected premium ingredients. Freshly smashed. Unmistakable flavour in every bite.
Our Story
More Than
Just A Burger.
Flatties isn't about simply selling burgers — we want to show how a real smashburger should taste.
That's why we rely on selected premium ingredients, regional partners, original Martin's Potato Rolls from the USA and high-quality Angus beef, refined with Wagyu fat and sourced from our Hinterhofmetzger in Staad. All of it rounded off by carefully selected premium sauces.
Every burger is smashed fresh and prepared only after you order, so taste and quality take centre stage without compromise. We question every detail, keep refining our products and pursue one goal: creating the best possible overall experience — day after day, with consistently high standards of quality.
The Difference Is in the Details
Quality You Can Taste
100% Traceable Origin
Local Swiss meat from Hinterhofmetzger in Staad — selected quality, transparent origin and responsible processing.
Better Beef
Selected Angus beef, refined with premium Wagyu fat — for maximum juiciness, intense flavour and perfect texture.
No Compromises
- No antibiotics
- No factory farming
- No growth promoters
- No preservatives
Original Martin's Buns
Original Martin's Potato Buns — imported directly from the USA. Soft, slightly sweet and unmatched in taste.
Premium Sauces
A curated selection of premium sauces — partly vegan, developed for maximum flavour.
All You Can Drink
Pay once — refill as much as you want. Mix it your way with lots of flavours, ice-cold & fresh from the Swiss Grapos system. No wait, just pour & go.
