Barcelona is famous for tapas, seafood and long Mediterranean lunches, but the city also has a strong burger scene, and smash burgers have become one of its most popular styles. Machaka | SmashBurger on Carrer de Balmes 165, in the Eixample, is one of the best-known names. It also has branches on Carrer del Consell de Cent and in Sants, so there is usually one not too far away.
What is a smash burger?
A smash burger starts as a ball of minced beef that is pressed hard onto a very hot griddle with a spatula or press. Flattening the meat this way gives it as much contact with the hot metal as possible, which creates a thin patty with a dark, crispy, caramelised crust and lacy edges. The patties cook in a couple of minutes, and two or more are often stacked with melted cheese in a soft bun.
The style comes from American diners and has become a global trend over the last few years. The appeal is texture: a smash patty is less about a thick, juicy centre and more about crunch, browned flavour and melted cheese.
What we ordered
- Smash burgers, served in paper bags on trays.
- Regular fries and sweet potato fries on the side.
The place
The interior is bright and playful, with colourful pop-art posters on the walls and the slogan “donde la magia sucede” (“where the magic happens”) painted on one of them.
The most photographed spot, though, is the bathroom: a small room lit in neon, which is something of a hidden surprise for first-time visitors.
What’s on the menu
Burgers are the main event, but the menu has a few other things worth knowing about:
- Smash burgers in different combinations of patties, cheese and sauces.
- Fries, both regular and sweet potato.
- Patatas bravas, the classic Spanish tapa of fried potatoes with a spicy sauce, here as a side.
- Milkshakes for a sweet, American-diner style drink.
- Churros for dessert, a Spanish favourite usually dipped in chocolate.
Ordering is done with a QR code at the table, so you browse the menu on your phone and send your order from there.
How to order a smash burger
- Single or double. Smash patties are thin, so a double is a common choice if you are hungry.
- Cheese matters. Melted cheese holds the patties together and balances the crispy crust.
- Watch the salt. Seared crusts and cheese can be salty, so ask about sauces if you prefer something milder.
- Share sides. Fries, sweet potato fries and bravas are easy to split between the table.
- Leave room for dessert. Churros or a milkshake are a natural way to finish.

About the Eixample
The Eixample (“extension” in Catalan) is the large grid district that was built in the second half of the 19th century when Barcelona expanded beyond its old medieval walls. It was planned by the engineer Ildefons Cerdà, and its blocks are easy to recognise from above thanks to their cut-off, octagonal corners, called xamfrans, which open up every crossing into a small square.
Today the Eixample is one of the main dining areas in the city, with everything from traditional bars to modern restaurants. Carrer de Balmes is one of its busiest streets, running uphill from Plaça de Catalunya towards the upper part of the city.
Nearby things worth combining with a meal here:
- Passeig de Gràcia, with its shops and modernist buildings such as Casa Batlló and Casa Milà (La Pedrera).
- Rambla de Catalunya, a pleasant, tree-lined street for an evening walk.
- Gràcia, the village-like neighbourhood just across Avinguda Diagonal, full of small squares and bars.
Getting there
- Diagonal (metro lines L3 and L5): a short walk.
- Provença (FGC suburban trains): also close.
- Many bus routes run along Carrer de Balmes and nearby streets.
The Consell de Cent branch sits in the lower Eixample, and the Sants branch is in the neighbourhood around Barcelona Sants station, handy if you are arriving or leaving by train.
