BEST QUALITY
Our smash burgers are made with carefully selected beef, toasted buns, melted cheese and fresh toppings. Every burger is cooked to order, hot, juicy and full of flavour.
COOKED FOR YOU
No shortcuts. No boring meals. Every order is prepared fresh so that every customer gets the same STACKD experience: fast, bold and made with care.
MADE FRESH DAILY
Our house sauce is designed to be the perfect pairing for burgers, fries and chicken. It is creamy, bold and made to give every bite the STACKD signature flavour.
MULTIPLE SIDES
Golden fries, crispy bites and loaded sides complete the experience. At STACKD, sides are not an extra detail — they are part of the main event.
NIL & GONZALO’S VISION,
OUR MISSION
CHASING THE DREAM
Nil Sierra and Gonzalo Vargas were students at ESIC University when they started imagining a burger concept that felt different: simple, bold, energetic and built around one idea — doing one thing really well.
2024
THE FIRST IDEA
Between classes, projects and late-night conversations, they started shaping STACKD as a brand made for students, friends and people who wanted proper comfort food without overcomplicating it.
2025
BUILDING THE BRAND
Nil focused on the creative vision and customer experience, while Gonzalo worked on operations, product structure and how to make the concept scalable. STACKD started becoming more than an idea.
WORKING HARD
The project grew through research, testing and constant improvement. Every detail mattered: the menu, the tone, the colours, the packaging and the experience inside the restaurant.
THE STACKD FORMULA
The founders decided that STACKD would be built around a focused menu: smash burgers, crispy chicken, fries, sauces and drinks. Simple products, strong flavour and a brand people could remember.
OPENING DAY
STACKD was created as a Barcelona-born concept with the ambition of becoming a meeting point for students, locals and burger lovers. One dream. One love. One stack at a time.
