There are some foods that simply refuse to be confined to one part of the day, and if Four Seasons Hotel London at Park Lane has anything to do with it, the humble croissant is about to become one of them.
The luxury Mayfair hotel has unveiled La Croissanterie, a new dining concept from acclaimed French chef Yannick Alléno that takes one of France’s most famous pastries and gives it a decidedly luxurious London makeover.
Located within Pavyllon Lounge, next to Michelin-starred Pavyllon London, La Croissanterie has been created around a wonderfully simple idea: croissants deserve far more attention than the fleeting few minutes we usually give them over our morning coffee.
Open every day from 12pm until 8pm, the new concept takes inspiration from Parisian café culture and the French tradition of slowing down during the afternoon for something delicious. But don’t expect a basket of standard butter croissants here. Alléno and his team have transformed the pastry into an entire menu of sweet and savoury creations designed to work for lunch, an afternoon catch-up or even an early evening bite.
This is definitely not your average croissant
Each croissant is hand-laminated and freshly baked before being filled with combinations that sound considerably more like dishes from a luxury restaurant than something you’d normally pick up from your local bakery.
Savoury options start from £15, with the Caesar Chicken combining roast chicken, anchovy and egg mayonnaise, crisp romaine lettuce, Caesar dressing and aged Parmesan.
For something even more indulgent, the Scottish Lobster Croissant, priced at £20, comes filled with lobster, egg mayonnaise, smoked pike roe and fresh tarragon.
Then there’s the Arabian Lamb, featuring 36-hour confit lamb shoulder with labneh, tomato and onion salad, while the Asian Wagyu pairs sautéed Wagyu beef with soy and sesame dressing and fresh vegetables. 
Vegetarians haven’t been forgotten either, with an option featuring guacamole, warm poached egg, rocket and Parmesan.
Essentially, Four Seasons has taken the croissant out of the breakfast basket and turned it into a proper meal.
And we’re not mad about it.
Save room for something sweet
Of course, it would be almost criminal to create an entire concept around croissants without giving the sweeter varieties their moment.
The menu includes an indulgent Hazelnut Chocolate Croissant, layered with chocolate ganache, salted caramel and chocolate shavings, alongside an Almond Praliné creation made with toasted almond cream, caramelised almonds and vanilla glaze.
Alléno’s signature chocolates also make an appearance, including a chocolate trilogy built around Tahitian vanilla bean, coffee and Breton shortbread.
If you’re planning on visiting simply for coffee and something sweet, you certainly won’t feel out of place.
And naturally, there’s matcha
Because no new London food opening in 2026 would be complete without matcha making an appearance somewhere.
La Croissanterie’s drinks menu includes Kagoshima ceremonial matcha, alongside colourful creations such as a Strawberry Matcha Latte and Mango & Coconut Matcha Latte.
Coffee lovers can choose from drinks created using an exclusive Lavazza blend developed for Pavyllon London, as well as cold brew, flat whites, cappuccinos and lattes.
There’s also an Earl Grey and Peach Spritz, sparkling jasmine tea and other tea-based creations from JING.
It all feeds into the feeling that La Croissanterie isn’t supposed to be somewhere you simply grab a pastry and leave. It’s designed for lingering.
Another reason to head to Mayfair
London certainly isn’t short of places to eat a good croissant, but La Croissanterie enters a rather different category.
This is the croissant as an experience.
It’s luxurious, slightly extravagant and perhaps completely unnecessary; which is precisely part of the appeal.
There is also something rather fun about seeing an ingredient as familiar as a croissant treated with the same creativity typically reserved for a full restaurant menu. Lobster, Wagyu and 36-hour confit lamb tucked between buttery layers of pastry may not be traditional, but they’re certainly going to get people talking.
And with London continuing its love affair with beautifully designed cafés, elevated bakeries, matcha bars and experience-led dining, the timing couldn’t be better.
The Sasha Edit
Would we pay £20 for a lobster-filled croissant?
We’d certainly like to find out whether it’s worth it.
What makes La Croissanterie interesting isn’t simply that Four Seasons has found another way to make something luxurious. It’s that it takes a familiar food and completely changes the occasion around it.
Croissants are no longer being positioned as something hurriedly eaten on the way to work. Here they’re the main attraction; paired with premium ingredients, ceremonial matcha, carefully made coffee and the type of surroundings that encourage you to stay for considerably longer than planned.
And sometimes, turning something simple into an occasion is exactly what London does best.
La Croissanterie by Yannick Alléno is now open daily from 12pm–8pm inside Pavyllon Lounge at Four Seasons Hotel London at Park Lane, Hamilton Place, London W1J 7DR. Walk-ins are welcomed subject to availability, and reservations can also be made directly with Pavyllon Lounge.
