Why the Supernova burger keeps winning London over

We’re firmly on a mission to find the best burger in London, and lately the Supernova burger keeps coming up in conversations (and late-night scrolling).

At this point, it feels less like a casual project and more like a personal calling. So when the stars align and we land a rare child-free Saturday (thank you, very generous sisters-in-law) the plan suddenly feels obvious. This is the day for a smashed Supernova burger date in Mayfair.

Supernova Mayfair and first impressions

Supernova has a new location that’s just opened up in Mayfair. It feels like the largest one so far, with plenty of seating and a mix of counters, booths and regular tables. We choose counter seats, mostly because we love watching burgers come together.

From here, everything unfolds in front of us. Patties hit the grill and get smashed hard, their edges frill and crisp. Yum.

The interiors add another layer. Supernova leans heavily into mid-century American diner energy, filtered through a modern lens. There are stainless steel surfaces, warm yellow laminate, terrazzo floors, and early-1970s-style banquettes.

With the soundtrack humming along in the background, the scene feels cinematic. At more than one point, we both think of Tarantino’s Pulp Fiction. It’s cool without trying too hard, and nostalgic without feeling dated.

The Supernova menu keeps things simple

One of the strongest things about Supernova London is restraint. The Supernova menu is short and direct, and that confidence is refreshing. You choose between the classic cheeseburger or the house cheeseburger. Then there are fries and the cheese dipping sauce. And if you’ve got space left (doubtful), you might finish with a sundae.

That’s it.

This kind of simplicity works especially well for a smashed burger London spot. It tells you that the restaurant believes in what it’s serving, and after eating here, it’s easy to see why.

We order both burgers, one portion of fries, and the cheese sauce, fully intending to share everything. It turns out to be exactly right.

The Supernova burger and the perfect smash

Both burgers arrive wrapped and satisfyingly heavy. Each one is built around two smashed patties made from a blend of dry-aged British beef. The patties are smashed aggressively enough that the edges become thin and lacy, almost crisp, while the centre stays juicy and rich.

This is where the Supernova burger really shines. The ratio of bun to cheese to patty is spot on. The bun is thin and soft, just sturdy enough to hold everything together. The meat dominates, as it should. The American cheese melts into every crevice, gluing the whole thing together without ever feeling excessive.

Every bite is brilliant.

Classic cheeseburger vs house cheeseburger at Supernova

The classic cheeseburger has mustard and ketchup, that bring sharpness and sweetness, while pickles and onions cut through the richness of the beef and cheese. It tastes familiar, like the best possible version of a burger you’ve always loved.

The house cheeseburger, on the other hand, leans into Supernova’s signature sauce. This version feels slightly creamier and rounder, with a deeper savoury note that pulls everything together. It’s richer, a touch more indulgent, and incredibly moreish.

Switching between the two keeps things interesting. One feels nostalgic and punchy. The other feels smoother and more luxurious. Neither outshines the other, which is exactly why ordering both makes so much sense ;)

Fries, cheese sauce, and total satisfaction

The fries arrive hot and golden, thin and crisp, with that ideal texture that stays crunchy all the way through. They’re excellent on their own, but the cheese dipping sauce takes things to another level.

The cheese sauce is thick, glossy, and deeply cheesy, closer to a proper nacho sauce than a flimsy dip. It clings to the fries beautifully, turning every bite into something indulgent and deeply comforting.

By the end, we’re properly full and comfortably satisfied in a way that lasts for hours.

Why Supernova stands out in London’s burger scene

There are a lot of smash burgers to choose from in London. Some are stacked high, others encourage you to add lots of bits. But I quite like that the Supernova burger keep things simple.

It focuses on great beef, a proper smash, melted cheese, and just the right type of bun.

It also helps that all the burgers are halal, which makes Supernova an easy and welcome option for anyone eating halal without sacrificing flavour or indulgence.

Final thoughts on Supernova London

By the time we leave Supernova in Mayfair, we’re already talking about when we’ll come back. That, more than anything, says it all.

This is smashed burger perfection done with confidence. The food is excellent, the setting is fun and atmospheric, and the menu is refreshingly simple.

If you’re on the hunt for one of the best burgers in the city, you won’t go far wrong with a Supernova London burger.
