Rumpus Room is a trendy bar in the Mondrian Hotel, but with actual good vibes and drinks. It’s pricey, but worth the cost for the view.

The Infatuation is an app and website which uses a small team of local editors who dine anonymously to rate and review restaurants. We are partnering with them to bring you their smart, helpful, trustworthy reviews of restaurants on OpenTable

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.

The views and ambience make this place. I found the service slow and on a number of occasions had to physically get up and approach a member of staff to get a drink although should be table service

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!

Visited on a Saturday night at 9 having booked in advance came with my daughter. We both felt comfortable and not ‘out of place’ despite the 30 year age gap !
Wonderful service, great staff ....everything was faultless !

Extremely slow service, we were seated and took 40 minutes to receive our first round of drinks. An hour and half into being seated we were constantly reminded our time is ending and we have to give up the table soon. As well, orders were missed yet we were charged for. For two hours of being seated and slow service we only managed to get two rounds of drinks which is not acceptable service.

We had a wonderful time at the Rumpus Room, celebrating a birthday. The Hungarian waitress we had was an absolute delight and went out of her way to help us, including making us a fruit plate when asked. The red wine was good and she changed one of our drinks without any questions asked when it wasn’t that great. Would recommend and return!

Stunning venue but service was very slow until the end of our 2-hour slot where we were then reminded every 5 minutes for the last half an hour that our time was running out! Never felt so ‘on the clock’. Cocktails were lovely but nibbles were very expensive considering other London bars provide these!

Extremely disappointed upon arrival by the poor and rude service provided by the gentleman/host at reception. I was running late and had telephoned to inform the same; was told it wasn’t an issue and that the table would be held. I arrived within 15 minutes of the reservation booking and upon arrival told that 1. I was lying about calling (and had to go through call log to prove this) and 2. There was nothing he could do as the table had already been given away. He was extremely rude and did not even think to offer an apology or look to accommodate us elsewhere.

We therefore had to find somewhere to stand which wasn’t a pleasant experience, especially as we had attended for a special occasion.

If you expect customers to provide their card details to book a table, the least your staff can do is apologise and try to be a little more accommodating when they mess up at their end.

Loved this place, once we got inside .....its very cool and has great view of the city and river in the evening. We got there at the opening time at 5pm but it wasn't open , staff were still faffing about getting ready so a queue formed at the door, once it opened at 5.10 it was made worse by the cloakroom guy insisting everyone go back to the reception desk to check in first with the maitre d ( who wasnt ready) - get your act together!! By the time we left at 6.30 it was packed so think reservations are needed
