Keystone Bar and Restaurant

Recently had a joint birthday party here with a friend and we couldn’t be happier with the service Di and her team provided for us in the build up to the event and on the night itself. We were given a bespoke cocktail list, had the place to ourselves, and excellent service from start to finish for our 50 or so guests. A really fun night!Food: 4/5

Great cocktails, friendly staff, and a good atmosphere. Recently hosted a birthday party here and the whole process was super smooth from start to finish; Di and the staff put on a great night for us. Thanks again, would recommend!Food: 5/5

It was a lovely Xmas party and this was a great location. Lovely staff and nice drinks too. Music could be a little less invasive however it was still a very enjoyable evening. PS: love the whole entrance bit Service: 5/5

It really is a lovely venue, looks really good and the idea is fun. But I cancelled my membership a few months back, partly because I just didn't use it enough for it to be worthwhile but partly because it didn't make sense that I was paying a membership and then being turned away because all the tables were taken up by non-members on trials of the venue. I understand that might be an important way to get new members but surely the bar should be looking after the existing ones a bit? It was also offputting to be asked repeatedly by two different members of staff if I was a member as though I was doing something wrong by being there - being asked once by one person should be enough. Not that being a member actually seems to make much difference. All that being said, it is a cool place so as long as you're never going to try to go for drinks spontaneously and don't mind being treated like a trespasser in a venue that you pay to be a member of it's definitely worthwhile!

Cocktails have gone downhill since a change of ownership. Still friendly service. But, they need to learn how to make a martiniService: 4/5

Great little venue with fab staff. Cocktails are pretty good. The venue used to be very cool but it needs to a lick of paint, a better stocked bar and to fix the speakers. Music kept cutting out but that might be because the owner was pushing the volume right up.

My first time visiting Keystone Crescent was brilliant. Truly fantastic cocktails their riff on an espresso martini blew my mind! served by fun, friendly and knowledgeable people. The decor is super cool, straight out of Mad Men, and it's sitting only, so you're not jostling a million people to get your drinks.

Organised my big birthday bash here and can’t recommend the place highly enough. Di, the manager, wanted to make sure I had a memorable and fantastic party and she went out of her way to make that happen. Honestly. No ask was too big, from being able to decorate the place to how I liked, to bringing in a six-piece band and all their equipment. It turned into quite an event!! All my queries were swiftly answered, the cocktails were fantastic, the whole bar staff team really friendly, and on the night, Di even threw in my own private photographer. Amazing! Seriously, everybody who attended loved this place and had a great night. It also just happens to be very cool n cosy and in a great location too. I wouldn’t hesitate to book the place again.

Wonderful evening in a very warm and inviting space with very friendly and knowledgeable staff. The cocktail masterclass was fantastic and even involved our son on line from Los Angeles for a short while. Amazing cocktails explained fully with no little humour that left us a little worse for wear but a truly great couple of hours. Would highly recommend. Book now !!

A stylish members club tucked up behind Kings Cross on Europe's smallest crescent. Super cocktails, friendly professional staff and a great spot to grab a late night cocktail, or two.
