Horrible service we ordered a bottle of champagne took a while for waitress bring it to the table and after he pour it
He left bottle on table ,, I have to call somebody else to ask to put bottle on a bucket “common sense “
Then I asked for a liquor he forgot , he never check on our table , the 2nd bottle I have to called to somebody else .

Beautiful place but the service was the worst

The service was awful, seemed to be a an effort for the waitress to serve us. You have a table for 2 hours and are swiftly told when you need to leave. Pretentious atmosphere, shame because the views are lovely.

Had a fantastic celebration drinks here, with a great band playing live music on Wednesdays! Cheese board was lovely too. Only let down was the man organising the tables could have been much friendlier, arrived early for our table and he made us feel awkward for staying the total time we had booked (had been booked weeks in advance)! Apart from this I would definitely return.

They've let this place go significantly. from the rude and flustered employee at the entrance to the general decor and set up. This used to be a great spot to enjoy good cocktails and music. The music and the cocktails are still great, but the staff are overwhelmed and poorly managed. The tables and seats were dirty and the clientele reflected the dropped standards. we left after a single drink.

Excellent interior design, music and friendly customers made a good vibe and somewhat unique atmosphere.

Cocktails were tasty and high quality. The suff seemed to me bit little too casual for a premium venue. As we entered, we were waiting for a few minutes until hostess finished showing pictures to a friend or colleague. Also, before we ordered drinks we were requested to either pay upfront, or open a tab which did not help pleasant experience.
On the other hand, apart of these few details, service was great, we enjoyed our time and I would happily recommend 12th Knot to friends.

This place is amazing!!! I would definitely go back. We reserved a table and the service was amazing. As it was a hot summers day we managed to get the swinging chairs on the balcony too - which was brilliant. Lovely views of the Thames and St. Paul’s. Cocktails were amazing too! Get yourself there!!!!

The view is very nice,the personnel is very kind and smiling.We had a reservation for 2,and they gave us a table without view,but after 10 minutes or less,they changed our table with one with view,and that happened without asking them. The drinks are not cheap,but you’re not in an ordinary bar,and after all,it’s London,and London is not cheap! Our experience at 12th Knot is was very pleasant.

Really disappointing experience with 12th knot. As soon as we arrived we didn’t feel welcomed at all. We were seated and asked the waitress if we could order drinks and she advised that another waitress would take our order. 15 minutes later still no one came to take out order so we asked another waitress who said that someone would be with us soon. Another table was seated next to us and they’re drinks order was taken. After still waiting and trying to get someone’s attention we gave up and we went up to the bar and ordered our own drinks. The drinks were completely overpriced for the size of the drink. The only enjoyable aspect of our experience was the view. Wouldn’t recommend here! Poor service and completely overpriced.

Cheeky live music especially on a Friday night. Beautiful decor and toilets were very plush. Thanks for having us. Scarlett

Made reservation for 7.30 pm two days beforehand. Received a confirmation email accordingly and subsequently turned up as per the booking only to be told that there was a private function that evening so we’re turned away at the door leaving it too late to make alternative arrangements. Received an automated email from the venue with no apology when they messaged to ask why I didn’t turn up?!!!..naturally I responded but again received no apology just another automated response..pity

Amazing service. The gentlemen Front of House (apologies, I don’t know his name but good dress sense, glasses) was so accommodating. We were a group of girls eager to see our friend that lived abroad and he could not do enough to accommodate the growing number of girls and champagne bottles and plates of food we kept ordering! They never let the venue get crowded like others keen to cash in on a sunny day in London. My only request is that they keep the terrace open later!

I have been wanting to go here for ages and I was actually really disappointed.
The place itself is hard to find and when we asked the reception staff how to get up to 12th Knot they said ‘just get the lift!’ We didn’t know where the lift even was. The place itself is really cool with amazing views. The cocktail menu is so limited with not much choice so we opted for gin and tonics which were very pricey. The service was poor, we sat for 15 minutes before anyone came to our table. Two strangers were told they could sit with us at our table (which I prebooked) without being asked and then they sat listening to our conversation so it was very uncomfortable so we decided to leave. Very disappointed.

Overall good value, crowd was upclass and views were amazing. Food options will do good to have more variety, they dont have option to walk up to counter and order and force you to wait for table service but at peak times will need to wait for 20-30 minutes to get attention of a server to order something (especially after your initial order), not sure if it was shortage of servers or because we didnt look westerners.

If you are a couple be prepared to be sat in the middle of the bar area on the sofa and the other person has to sit on a stall for 2 hours. It is really cramped and conversations either side of you totally overheard. Was really looking forward to trying this bar, my recommendation would be if you're a couple go on a warm day & sit outside or just go as a group to get a better table around the outside.

This is a beautiful bar with delicious cocktails. A bit pricey so maybe more for a special night out or when you're trying to impress (seemed to be a lot of first dates going on). Really friendly and happy staff. It must be a great place to work.

If you want a beautiful view and excellent cocktail, then I recommend. There was a very limited menu of food the night we went. This is not a restaurant to go to for dinner in my opinion and that is not clear. The cocktails while good are pricey.

I had to cancel my cab twice because they made a mistake and I had to wait almost 20minutes just to pay. The whole evening was going good until the time it came to pay the bill. I asked the waitress that was serving us initially, she disappeared. I asked another one and she said she will get it and vanished again, so we had to get up and go to the counter to ask for our bill and even after that no one told us there was an issue with the system or what the hold off was so we were just standing around in the middle embarrassingly just to pay. I will never come back again!
