Very nice atmosphere, relaxing and comfortable. Cocktails are good. Cosmo Highball is a relatively light one with no strong alcohol taste, perfect for my choice. Will definitely visit here again. Even just for coffee and tea will be good!

Oh, I fell in love with this new London bar! The energy is delicious and bouncing on a Saturday night. The cocktails are fantastic and the team working there are stellar. This place is both upscale and cozy and you immediately feel right at home. Cannot wait to return.

I had the most amazing and unexpected surprise running into this fine establishment tucked away just a stone throw’s distance from Green Park station. Kwant was tasteful, sophisticated yet familiar. The friendly and enthusiastic team makes you feel right at home, never shying away from sharing their passion for their signature cocktails. I had the most wonderful experience with Giusie, who was so authentically welcoming and knowledgeable about the menu and found the perfect drinks for us. I had skin contact, and it was love at first taste. Not much of a drinker myself and I can tell this drink was as delicious as it was dangerous, it was almost addictive. I would definitely come back and recommend this place to all of my friends.

I had the pleasure of stumbling upon Kwãnt bar by chance when my initial destination was fully occupied, and I couldn’t have been happier with the fate of the experience. Tucked away under scaffolding, it’s an easily overlooked gem that I wholeheartedly recommend visiting. My visit to Kwãnt was timed just before a private viewing at RAA, and it was the perfect spot for a quick drink. The atmosphere inside is nothing short of fabulous. The interior is stunning, creating a relaxed and inviting mood. The attentive service adds to the charm, making it a memorable experience. The venue is gorgeous, but because of dimmed lighting, it is hard to photograph. One highlight was the exquisite snack menu. I opted for a non-alcoholic Spicy drink, and my friend received expert guidance to choose a flavorous light drink. To accompany our drinks, we selected a plate of cheddar cheese. While it’s worth noting that prices in Mayfair can be higher, the quality of the experience justified it. The drinks may be smaller, but the taste and ambience more than makeup for it. Kwãnt bar has left a lasting impression on us, and we will undoubtedly be returning for its exceptional atmosphere, friendly and attentive staff, and delicious flavours that make it a hidden gem in London.

It wasn’t easy finding kwant but when I did and when I opened that door to reveal the gorgeous underground bar, my mouth dropped wide open. I was not expecting to be transformed back to...1900s with a touch of swankiness yet without the air or arrogance. Perhaps the Bartenders made an effort in contributing to that. My drinks were all meticulously done and while their drinks may look simple - youre really sipping into a pack of flavours. They’re a new entry on this years top 50 bars and I sincerely look forward to them rising up to Top 10.

A unique cocktail and drink bar with a nice atmosphere, friendly service and simply outstanding drinks. The ice and service were resounding. Visit this place if you'd like to impress someone or just a lovely drink, you're in for a treat!

I had the pleasure of visiting Kwant last week, and I am thoroughly delighted with the impeccable service and exquisite cocktails. The cocktails surpassed my expectations, showcasing an unparalleled level of craftsmanship and sophistication. The expertise and artistry behind each cocktail undoubtedly contributed to a remarkable experience. The staff exhibited exceptional friendliness and attentiveness, delivering a top-tier service. I wholeheartedly recommend Kwant to connoisseurs and enthusiasts alike. Truly an establishment of distinction.

Kwant was supposed to be the highlight of our night, as one of the most anticipated cocktail bars in London. However, the servers were terribly ill-mannered. My friend and I each ordered two cocktails and drank at the counter, fully aware that the spot was reserved for a later time. Instead of kindly reminding us to move to a different table, the server rudely told us, 'You need to move right away,' even when we stood up and asked for the bill. Moved to a table by the door, we quickly asked for the bills. Another server, holding other people's coats, asked me to scooch forward so he could pass. Despite taking barely any space at 5'4", I was asked to move specifically when there was another guy sitting behind me, with the entire bar very empty. I felt specifically targeted as an Asian female. As someone who lives in London, I can't accept other customers, whether local, tourists, male, or female, to be treated this way. I stood up and asked the server if he asked the guy behind me, to which he lied and said yes. A well-established bar charging £18-plus per cocktail should have better-trained staff. High ranking doesn't mean you have the right to mistreat your customers. It's unacceptable. I don't recommend this place.

Superb atmosphere, unbeatable cocktails, and service which makes you feel transported. A must visit when in London. No wonder it made into the World’s 50 Best Bars this year within just weeks of opening!

Great bar with a nice atmosphere and superb service. All cocktails we tried were excellent. One of the few in the neighborhood that stay open late (till 1am) The bar is hard to find, you have to enter from the side door of another bar, no label or whatsoever. Still it’s worth asking for it.

Fantastic cocktails with a cozy atmosphere. Always My favorite cocktail choice in central London.

Classy, low-key, cocktail bar. Also friendly staff, willing to help. If you’re looking for classic cocktails this is the place, for more experimental cocktails I would go to another bar.

One of the best bars in London, our server Gento was the most attentive and knowledgeable servers/bartenders I’ve ever seen. Most incredible cocktails I’ve ever tasted with all their unique qualities. The service at this place was unparalleled.

Kwãnt is truly something special - perfectly well-balanced just like a great cocktail ought to be. On that note, their cocktail list is enormous and every single one that I tried was outstanding - delicate, flavourful, and exciting. The atmosphere is pleasant, woodsy, and is neither too bright nor too dim. I found the service to be friendly and polite without being overbearing. Although the cocktail bar market is exceptionally crowded in London, Kwãnt manages to truly stand out. I am delighted to have a bar like this in my neighborhood and I very much look forward to my next visit.

Andrea made such a great dry martini - and the chef’s table is epic!

My husband and I had an absolutely fantastic night at Kwãnt. We went for their tasting menu and it was sensational! The cocktails are also top tier and the service was incredible. We would highly recommend, and will definitely be returning! Special shout out to Gabriel who was fantastic - we had to run for our Uber and could not thank him directly for being so great. Thank you Gabriel!

Kwānt is back and (whisper it..) better than ever. The astonishingly great cocktails that you’d expect from Eric Lorincz and his uber-talented team along with smoothly professional but also warm, friendly and welcoming service - now enhanced by amazingly good snacks from chef Joni Ketonen. Truly world-class.

Beautifully decorated cocktail bar in Mayfair with a unique and extensive cocktail list, the margarita was fantastic. Super friendly service too.

A great space for world class cocktails and michelin starred snacks. Genuine hospitality and very well curated details

Great concept and drinks quality, vibrant atmosphere.

No doubt the best cocktail bar of the year. Lovely cocktails, lovely staff, (Jucy was genial!), elegant venue. Garden Martini with Sipsmith Gin was top!

The drinks here were superb, some of the best in London. The menu is well considered with lots of interesting ingredients and combinations. There’s obviously a lot of care that’s gone in to the drinks. We had a reverse martini type drink and one with miso flavour. The martini was delicious but the star was definitely the miso drink, 100% savoury and really amazing. The decor is very cool, and well done. It’s tucked away under Momo so a little hard to find. Service was super attentive, non intrusive with just the right amount of interaction explaining drinks.

Excellent service and drinks.

This place is amazing. The staff goes above & beyond to talk to you, find out what you like, and make you the cocktail of your dreams. And it’s BEAUTIFUL inside. I went twice while I was in London and determined it’s my new favorite cocktail spot.
