Offbeat dining: the best quirky restaurants in London

At times, we all need something refreshing and different to step away from typical eating out. For those special moods that may strike you, I’ve rounded up a list of establishments that fall somewhere between unusual, eccentric, and downright weird. It’s no easy feat to keep the balance, but these spots have truly mastered the art and are definitely worthy of the Best Quirky Restaurants award.

1. Attendant Coffee Roasters - Fitzrovia

I willingly headed to grab a cup of coffee in a Victorian toilet. And as a fan of everything repurposed, I’m totally won over by Attendant Coffee Roasters, tucked away in an underground gentlemen’s lavatory built at the end of the 19th century in the heart of Fitzrovia. A beautiful wrought-iron gate invites you to walk down a flight of stairs to enjoy specialty brews, single-origin filters, as well as nourishing breakfast and brunch treats. I highly recommend pistachio latte and avocado & halloumi roll — both are on point. As you can imagine, the interior is pretty special, with original porcelain urinals turned into counter-style seating, complete with comfortable bar stools. A lot of effort went into making a public loo feel cozy, but its past is still easily recognizable, with its tiling and light fixtures intact. Just keep in mind, though, that the space is tiny and often gets crowded — something to consider if that might bother you.

Avocado & halloumi roll — £7.8

2. Karen's Diner

If you’re an actual Karen, maybe skip this one — there’s really no point in speaking to the manager here. If you’re not catching what I’m saying and/or are easily offended, it's best to steer clear, too. At Karen’s Dinner, your worst service nightmares come true and get the full spotlight. You know those 1-star restaurant reviews that moan, “the staff was rude”? Here, they’ve taken that feedback and turned it into their hallmark. So what does all that mean? Well, the menu features insults, harsh jokes, and an intentionally abusive attitude from the charming ladies who serve you. People seem to have a blast, laughing it off, but honestly, it’s not quite my thing, and I mostly felt a bit awkward. Anyway, it all depends on your mood and sense of humor, and it’s still definitely something to try once, especially with a good crew. The kitschy interior adds to the vibe, as if it’s shouting right back at you. As for the food, keep your expectations low — it’s all about burgers, BBQ wings, hot dogs, and fries, plus decent milkshakes and cocktails to round it out.

The Basic Karen burger — £22

3. The Little Blue Door

Behind The Little Blue Door, you'll find a friend's cozy flat. Which friend? Who knows! It's just a house party where everyone’s invited. Make yourself at home, relax, and do whatever you like: take a bite, enjoy great cocktails, play Nintendo, dive into board games, or shoot some pool, all while casually overlooking those socks hanging to dry. In other words, like at a real party, introverts can curl up in one of the comfy sofa nooks while extroverts mingle and socialize at the bar. I really love how the team has captured the flatshare concept not only in the decor but in the overall ambience, which includes adorable, relaxed yet professional staff. And I’d totally book their private room for a birthday event because, among other things, their cuisine is surprisingly top-notch. I’ve been there for bottomless brunch, and pancakes with caramelized banana as well as halloumi buns were absolute winners. With a variety of drinks to choose from, go for rum punch — you won’t regret it!

Caramelized banana pancakes — £11

4. The Murdér Express

For fans of immersive performances and fine dining, The Murdér Express combines both in a truly masterful way. I love the romance of train journeys, and this spot invites guests aboard a stunningly realistic retro train departing from Pedley Street Station. Though you remain firmly in place, the “windows” (actually screens) create a moving landscape that feels like you're really traveling. Soon enough, you’re drawn into an intricately woven murder mystery brought to life by an expert cast. Without spoiling anything, let’s just say the 1920s aesthetic is brilliantly executed, right down to the smallest touches. I never miss a chance to dress up in the era’s style, and it was great to see other passengers in vintage outfits too. No complaints about the food — the four-course menu was well-crafted, with solid options for vegetarians, and the cocktails were flawless.

Adult ticket — £79.60
