Las Iguanas - London - Royal Festival Hall London

There’s a certain magic to the Southbank, that stretch of London where the Thames feels like a living, breathing thing. It’s a place for slow Sundays, spontaneous art, and the gentle hum of city life. And right in the thick of it, under the iconic roofline of the Royal Festival Hall, sits Las Iguanas—a vibrant, slightly chaotic, utterly charming bolt-hole.

This isn’t your average chain restaurant. Plonked inside one of London’s most beloved cultural landmarks, Las Iguanas feels more like a cleverly staged party. The floor-to-ceiling windows offer a front-row seat to the river parade: joggers, street performers, and the occasional over-dressed tourist.

The energy is effortless. You can pop in for a post-gallery mojito, a lazy lunch with friends, or a pre-concert dinner where the cocktails arrive faster than the main course—and that’s part of the charm.

The Why It Works

Location, obviously. But it’s the vibe that seals the deal. The decor is a riot of Latin American colour—splashes of turquoise, warm oranges, and rustic wooden tables—mirroring the eclectic mix of people inside.

It’s the kind of place where you can wear ripped jeans and a silk blazer, and no one bats an eye. A cultural crossroads between an exhibition at the Hayward Gallery and a jazz gig at the Queen Elizabeth Hall.

And let’s be real: after staring at abstract art for an hour, you need a plate of loaded nachos and a frozen margarita. This place delivers that without any pretence.

Order Like a Local

Don’t just scan the menu—dive into the specials. The “Tacos de Pescado” are consistently good, battered fish with a zingy slaw that cuts through the richness. The “Moqueca de Camarão” (prawn stew) is a warming, coconut-heavy hug on a rainy London day.

For a quick bite between shows? The “Quesadilla de Pollo” is a safe, satisfying bet. But the real star? The cocktail list. Their Caipirinha is dangerously good, and the “Pornstar Martini” is a crowd-pleaser for a reason.

Practical tip: Book a table on the mezzanine level if you can. You get a bird’s-eye view of the bar action and the river, minus the noise of the main thoroughfare.

The Cultural Crossover

Here’s a fun fact: The Royal Festival Hall was built for the 1951 Festival of Britain, a post-war celebration of optimism and design. Las Iguanas, arriving decades later, somehow fits that spirit—unpretentious, alive, and welcoming to all.

Another: The original Las Iguanas opened in Bristol in 1991, a nod to the owners’ travels through Latin America. This branch, however, feels uniquely London. It’s a bit loud, a bit messy, and utterly inclusive.

Think of it as the culinary equivalent of a Southbank busker: not perfect, but full of heart. And just like the Thames tide, it ebbs and flows with the city’s rhythm.

When to Go

Weekday lunch is the secret. The crowds are thin, the light through the windows is dreamy, and you can actually hear your companion talk. Sunday brunch? Arrive early. By 1pm, the place is a joyful zoo of families, hungover art students, and tourists snapping photos of their pancakes.

For a pre-show dinner, book at 6pm. The service is quicker, and you’ll be out by 7:30pm with a happy buzz. If you’re catching a film at the BFI IMAX nearby, the 20-minute walk along the Southbank is the perfect digestif.

And if you’re solo? Don’t overthink it. Grab a seat at the bar. The bartenders are chatty, and you’ll likely end up swapping travel stories with a stranger from São Paulo.

Beyond the Burrito

This place isn’t a destination for culinary epiphanies. It’s a setting. A backdrop for the real show: the ever-changing human parade of London life. The couple about to see a play, the freelancers nursing laptops over bottomless coffee, the retired gentleman reading a newspaper with a rum in hand.

It’s a reminder that the best experiences in a city aren’t always the Michelin-starred ones. Sometimes, they’re the ones where the salsa music is a little too loud, the chips are a little too salty, and the view of the Thames makes everything feel possible.

Practical Quick List

Address: Royal Festival Hall, Southbank Centre, Belvedere Road, London SE1 8XX. Nearest Tube: Waterloo (Jubilee, Bakerloo, Northern) or Embankment. Book ahead: Especially weekends and for events at the Southbank Centre. Dietary note: Solid options for vegetarians and vegans; just ask for the “vegan menu.”

Pro tip: Check the Southbank Centre’s event calendar before you go. You might catch a free outdoor performance right outside the hall’s main entrance. Combine that with a happy hour cocktail, and you’ve got a perfect London evening for under £30.

A Final Slice of Daily Life

On a Tuesday evening, after a long day of meetings and Tube delays, I found myself here, alone. I ordered a single taco and a glass of crisp Chilean Sauvignon Blanc. I watched the sun dip behind the London Eye, painting the sky a bruised pink.

It wasn’t a monumental moment. No grand revelation. Just a quiet, perfect half-hour where the city felt like a warm, familiar blanket. Las Iguanas at the Royal Festival Hall isn’t trying to be anything other than a place to be. And sometimes, that’s exactly what you need.

So next time the Southbank calls, don’t just walk past. Step inside. Let the music wash over you. Order something with spice. And remember: life is too short for boring meals in beautiful buildings.
