(CNN) — Fancy an afternoon tea while in the British capital? There's no better place to try this English tradition than in London, which serves up some of the world's most well-regarded versions.
Reputedly spawned when an English duchess made a simple request for cake and tea before dinner time in the mid-1800's, afternoon tea has since become a more decadent occasion.
Plush baked scones, assorted finger sandwiches and desserts with a generous pot of tea is now the modern standard. While London's traditional luxury offerings could easily monopolize this list, we've included quirky, novel options for those seeking teas with a twist, including one set on a vintage double-decker bus and a fanciful version inspired by Alice in Wonderland.
Fortnum & Mason
No one knows tea like Fortnum & Mason, London's premier tea and assorted goods emporium since 1707. Visitors can sample their famous teas and much more in the airy, elegant Diamond Jubilee Tea Salon, which is often filled with music from a live pianist. "Walking into the tea room felt as if I was walking onto a set for a BBC series set in the 19th Century," says That Adventurer blogger Hannah Kacary.
Tea sommeliers ask guests for taste preferences and recommend the perfect sip from an extensive menu. Also on hand are traditional sommeliers who assist in champagne pairings.
Save room for dessert, however. Fortnum's signature cake cart allows guests to choose a slice from a range of choices.

Sketch: A "candy shop" of cakes
Sketch's Gallery room -- enshrouded in pink and full of artsy flair -- is perhaps the city's most striking venue for afternoon tea. "You feel like you're in a candy shop, with the bubblegum pink seats and little cheesy messages at the bottom of your cups and plates," says Fresh and Fearless blogger Aftab Pathan.
Tea comes with finger sandwiches, such as the addictive comte cheese panini, warm scones and sweets such as cassis cheesecake and citrus meringue. For full-on eccentricity, there's the Sketch Exotic Tea, where the staff will strain Sketch's own brand of Champagne over chai, vanilla or Earl Grey tea leaves over ice.

It's no surprise that The Goring's afternoon tea is a classic, regal affair, given that the hotel's been a favorite of the Queen for decades (it's just two blocks away from Buckingham Palace).
Tea takes place in a lounge with gilded ceilings, velvety red walls and a crackling fireplace, and the selection of cut sandwiches and sweets -- salmon sandwiches with creme fraiche, strawberry-pistachio macarons and mini banana cake loaves -- change regularly.
Those wanting a premium experience should opt for the Afternoon Tea with Bollinger Rose Champagne, which comes with a plate of fresh-cut strawberries and cream in addition to all the fixings.

Mad Hatter's Tea, Sanderson
Alice in Wonderland's legacy lives on at the trendy Sanderson Hotel, hosting one of the city's most beloved themed afternoon teas.
Save for the round of savory nibbles, no element of this tea goes untouched without dashes of whimsy -- from the five "Alice" character-inspired tea selections to macaroons guised as animated pocket watches.
"The menu is hidden inside an old vintage book, teapots come complete with crowns... we tumbled down the rabbit hole and didn't want to return to reality," says Crummbs blogger Stacey Smith.
Those wanting their fantasy tea a bit more grownup can opt for the Mad Hatter's Tipsy Evening Tea, which includes four cocktail flights and boozy cake bites.

Bea's of Bloomsbury
The Bea's bakery brand hosts the most casual and affordable afternoon teas on this list, costing around half as much as other top-rated teas in the capital.
The tea menu is kept short and sweet with seven loose leaf selections, and sandwiches are replaced with an assortment of mini-brioches such as Parma ham with mascarpone and avocado with spiced yogurt.
Naturally, the bakery's strongest suit is the dessert selection, which includes dainty meringues and marshmallows, brownies and cupcakes. Bea's has expanded to multiple locations in the capital, but afternoon tea is only available in St. Paul's, Marylebone and the original cafe in Bloomsbury.

The recent 10th Anniversary collection features the famous McDonald's-inspired Moschino bag -- Pret-a-Portea's edible version is a sponge cake wrapped in red chocolate -- and stiletto cookies inspired by the likes of Nicholas Kirkwood.
There are no scones with this themed tea, but that hardly matters given the ample amount of haute treats and savory bites on offer. An afternoon tea in the British fashion capital that's always on trend.

Cahoots Squiffy Picnic
Cahoots: Putting the tea in party
An immersive underground "bunker bar" that hosts the novel Squiffy Picnic on Saturday afternoons, Cahoots transports guests to post-WWII. "We enjoyed our sandwiches, scones, treats and vintage goodies all served in wicker picnic baskets... we felt like we had stepped into a vintage wonderland," says Binny Shah of Binny's Kitchen.
Squiffy Picnic stretches the boundaries of the afternoon tea concept, as teacups are filled with hooch instead of Earl Grey, and entertainment comes from flirtatious singer Lois "Legs" Laurelle.
Those in particularly high spirits can go for the Hollow Legs, which provide bottomless booze, or a bottle of Moet & Chandon Champagne.
Worth noting that at entry -- guests must request "the captain" before accessing this speakeasy, which is strictly for those 21 and older.
