Sold Out Burger, a Parisian eatery established in 2020 in the 10th arrondissement, boasts a unique concept: offering just one beef burger a day, with an emphasis on daily ingredient preparation and minimal food waste. Their compact restaurant exclusively serves to-go burgers, with their Cheese Burger featuring aged cheddar, red onions, pickles, and secret sauce. We suggest you go all the way and upgrade your burger with double beef patties, bacon, and a side of French fries, as the end result is kind of amazing. The burger comes with thick and well-seasoned beef patties with a crisp crust, a soft and buttery bun, house-made pickles providing a balanced acidity, and a classic burger sauce. Thickly cut red onions add texture, and the added bacon tops it all off. Despite offering limited burger options, this classic and uncomplicated burger joint serves the best hamburger we've eaten so far in Paris.

The burgers arrive with an In-N-Out-style presentation, and this homage is evident throughout the meal. The bun-to-patty ratio is ideal, the potato bun perfectly toasted, and the well-seasoned crust highlighted the beefy flavours.

The burgers arrive in practical paper pockets that capture the beef juices from the perfectly cooked medium-rare patties. The bun's soft interior and griddled warmth pair harmoniously with the other ingredients.

Encarnado Burger, currently the most talked-about burger joint in Rio de Janeiro and crowned as the city's best by both Veja Rio and the burger guide Hambúrguer Perfeito, impressed us during our visit to the lively neighborhood of Ipanema. Their short menu features six burger options, and our Palhaço Reencarnado (meaning "reincarnated clown") was meticulously cooked and assembled. The golden brown sesame seed bun was not only visually appealing but also exceptionally soft and well-toasted. The balance in size, particularly with the substantial beef patty, and the well-proportioned ratios make it super special.

With around ten burger options on the menu, we sampled the Oasis, Picanto, and Brooklyn, experiencing burgers with both thick and thinly smashed beef patties. They offer the choice of one thick or two smashed patties, and the burgers are impressively saucy and feature a fluffy brioche bun that handles the beef juices impeccably. The dry-aged Rubia Gallega beef patties, aged for 60 days, are tender with a perfect pink centre and a generous crust.

The burgers served are well thought out and built with expertise and love. The beef is what really steals the show – a combination of crispy crust and decadent meat juices that dance on our taste buds. The short but sweet menu contains everything from classic cheeseburgers to wild lingonberry creations, and the common denominator is that everything tastes amazing. Gotland Smash has wowed locals and tourists alike, serving up top-notch fare regardless of the season.

In 2021, they also expanded to Brooklyn, and their menu offers burgers, sandwiches, hot dogs, and milkshakes. Out of their burgers, the Harlem Classic and Hot Mess were real standouts.

Nowon, New York City's first Korean-American gastropub, opened its doors in 2019, with locations in the East Village and Bushwick, Brooklyn. Emphasizing their unique influences in both decor and menu offerings, the restaurant is buzzing with a bustling atmosphere and loud music. We sampled two distinct burgers: the Legendary with two beef patties, cheese, roasted kimchi, pickles, onions, and kimchi sauce, and the Dry-Aged Steak Burger with the same ingredients but featuring a thick dry-aged 8 oz beef patty. We also loved their Nowon Fried Chicken with gochujang. Both burgers were super tasty, and the well-toasted, fluffy buns carried a subtle savoury sesame flavour. While the burgers were a bit messy in composition, the fusion of Korean flavours enhanced the overall experience without being overwhelming. A hint of heat added to the background, not overpowering the taste.

Lagom, helmed by Swedish descendant Elliot Cunningham, has been a beloved burger joint for Burgerdudes since 2017, and we had them as guests at Stockholm Burger Fest 2018. They've consistently earnt recognition as one of the UK's finest, and the fire-focused concept has made a triumphant return to Hackney Church Brew Co. in north-east London. Their amazing Smash Burger features dry-aged beef, American cheese, vinegar slaw, and a dill and mustard mayo. Even though the burger seemed somewhat small in size, the exceptional flavours exceed expectations, with expertly balanced composition. The beef, notably fatty and imbued with rich dry-aged notes, is exceptionally juicy and delectable. A stunning crust provided a satisfying crunch, harmonizing beautifully with the creamy cheese and tangy coleslaw alongside Scandinavian mayo. The simple, well-toasted bun played its part seamlessly.

Located in northeastern London in the Leytonstone area, Leytonstone Tavern recently gained recognition in England's burger scene.

We were delighted by the beautiful presentation of the burgers, with every element gleaming. The buns are soft, well-toasted, and generously seeded, while the patties, with a perfect balance of crustiness and juiciness, showcase the rich, dry-aged flavours. The thoughtful seasoning and harmonious flavours in both burgers stand out, with the cheeseburger displaying a well-balanced profile. Although the roasted bone marrow in the Bone Daddy was more of a stunt addition, the messy, decadent burgers has left us with a lasting impression.

Here they offer a diverse burger menu, along with delectable sides and shakes.

Au Cheval serve Chicago's best burger, but their Manhattan location is no slouch either, serving up some of the best burgers New York has to offer. We just love their classic Double Cheeseburger with American cheddar, pickles, onions, and dijonnaise. We usually skip the "au cheval" style egg, and instead opt for some pricey but delectable bacon. The experience delivers an exceptionally beefy flavour, complemented by the creamy cheddar, well-balanced dijonnaise, and crisp pickles. The patties are bursting with intense flavour, tender texture and impeccable seasoning. And the thick bacon provides a delightful buttery saltiness that elevates the burger to new heights. Book a table and come prepared for a hefty bill and loud music, and you won't be left disappointed. And if you're in Chicago, don't miss their more accessible Small Cheval locations across the windy city.

The burgers are impressive, with a savoury brioche milk bun hybrid, which pairs perfectly with the intense Rubia Gallega beef patties that melt in your mouth. Hundred Burgers have bowled us over, and serve the best burgers we've eaten in Europe. They're worth the flight to Spain alone.

Yes, the world's best burger restaurant can be found in a pizza parlour. Pizza Loves Emily have locations in both West Village and Brooklyn in New York, and has been our firm favourite ever since we first tried them back in 2017. Several visits later, we still dream about The Emmy Double Stack Burger, with two dry-aged beef patties, cheese, fried onions, pickles, and Emmy sauce in a pretzel bun. Every bite fills us with awe, and the bespoke Emmy sauce steals the show every time. It's richness and discrete spiciness works flawlessly with the other ingredients, creating a perfect harmony of textures and flavours. The pretzel bun defies expectations by being surprisingly soft, and its saltiness complements the burger well to allow the beef's deep and juicy flavours shine properly. Time after time, Pizza Loves Emily still retains its title as the best burger in the world, offering an unmissable dining experience (alongside their excellent pizza).
