The supermodel let off some steam at the hotspot after walking in the much-anticipated Victoria's Secret annual lingerie show the previous day.
The 33-year-old Brazilian was definitely prepared for the winter weather in a chunky, brown furry coat while carrying an embellished clutch under her arm.
The mother-of-two's incredibly long pins were dressed in a high-waisted pair of black leather trousers, which were teamed with heeled boots.
Keeping her dark tresses tied back in a relaxed up 'do, Alessandra accessorised with a pair of statement earrings and natural make-up.
She tweeted her 1.16 million fans earlier on to say: 'The greatest catwalk on earth @victoriassecret Thank u @ed_razek to make it happen!'(Sic).
Also in attendance at the A-List eatery was singer Natalie Imbruglia, who looked particularly chic in a strapless jumpsuit and tuxedo jacket.
Courtney Love also stuck to the wintry hue in the form of a patterned dress, however she made sure she brightened up her ensemble with an unusual print jacket.
Made In Chelsea stars past and present were also spotted heading in, including Victoria Baker-Harber and Emma Miller, as well as Marianne Faithfull and Carrie Fisher.
She made waves on the catwalk on Tuesday, showing off her svelte shape in a dazzling $2m Dream Angels Fantasy Bra, before heading out in a VERY tight lattice-style dress.
But Alessandra showed she can do casual just as well as glam when she headed out to a London studio the morning after.
Wearing a pea green coat and clashing blue metallic trousers, the stunner was almost make-up free as she headed to what appeared to be yet another photoshoot.
She threw on a baggy striped T-shirt which looked casual yet chic and covered her no doubt tired eyes behind a pair of sunglasses.
Shunning heels for an altogether more sensible style of footwear, she polished off her look with a pair of scuffed cream ankle boots.
The night before, post-show, Alessandra was clearly still set on displaying her perky assets, as she donned a low-cut, clinging checked dress while arriving on the pink carpet.
The saucy sleeveless number featured multiple sheer panels and sparkling black beads.
The mother-of-two paired her dress with shiny black pumps that matched perfectly, as they also included see-through details.
Completing her evening look, Alessandra sported a few statement rings and styled her brunette locks into a sleek straight 'do.
The Brazilian bombshell was wearing similar make-up as she had on during the VS show, featuring a dramatic eye, peach cheeks and a pink pout.
Alessandra was of course joined by her fellow Angels, who appeared equally as gorgeous in their post-show ensembles.
Adriana Lima, 33, displayed her toned figure in a chic black and white dress cut-out dress adorned with silver accents.
Meanwhile, Candice Swanepoel and singer Taylor Swift, who performed at the show, arrived in elegant yet promiscuous white gowns.
Taylor, 24, was clad in a long-sleeved dress featuring a thigh-high-slit and sheer beaded bodice.
The Blank Space crooner coordinated her look with her signature scarlet slick and heavier eye make-up than usual.
Candice, 26, was spotted in a plunging, see-through lacy floral white gown while opting for a minimalist look with her make-up.
Doutzen Kroes donned an ensemble similar to the South African beauty, arriving in see-through black pieces embroidered with flowery black accents.
Showing skin was certainly a theme of the evening, as even Lindsay Ellingson, 30, arrived in a black dress featuring a sheer blouse that completely gave way to her black bra.
Karlie Kloss, 22, covered up a bit more than her peers, wearing a high-collared sleeveless white dress that was pulled together with a black bow around her neck.
The fitted garment also featured a thigh-high frontal slit, showing off her lean legs and black stilettos.
CBS will air the show in the US on December 9 at 10pm.
