Cocktail Cavern at Dirty Martini Hanover Square

Venue planner was great, venue staff really good, helpful and barman was great with guests and keeping on top of everything like ice etc. no complaints at all. Happy hour is great and kept costs manageable but still gave a special feel allowing guests free choice of drinks and cocktails.

Room was freezing when we arrived but warmed up once filled up a bit, not sure how you'd fit 60 people in there though, id advise that would be awful as we were already crammed with about 30ish for this type of networking event, id say 40 max for a corporate event in the cavern - social perhaps more but def not corporate if id had 60 people in that room it would have triggered complaints.

Really great communication from start to finish with the team, especially the event manager. Well run on the day with smooth food timings and bar service who worked well given the demand. The packages on offer and prices were reasonable and helped make the event very inclusive. Really appreciate how helpful everyone was, especially the management in allowing some external catering due to religious reasons as well as general helpfulness in making the event a success and would definitely recommend the space and services.

Could’ve been good to have had the cloakroom open but that’s the only negative!

Good value and great service all night.

The loos were blocked for a part of the evening

Dhebora was very quick to respond and very helpful with the planning of the evening. The venue and space was small enough if fewer people had turned up but also when more arrived they could overspill into the main bar. Venue also had a really cool decor. Canapés tasted fantastic. Everyone seemed to enjoy the cocktails! Staff were extremely nice and friendly and willing to help. Smashed the minimum spend.

Had multiple complaints days later that the beers were served warm. Some staff had to YouTube how to make some of the cocktails. There was a change to the canapé menu on the night. I had arranged prior for the canapés to be out at 2015 but by 2045 they still weren’t out and I had to ensure that the staff knew we had ordered them and that they needed to come out which was strange as my brother in law had already O.K’d a change in the canapé menu. Unlike other venues the deposit is used as the minimum spend and isn’t returnable. Area wasn’t roped off as discussed.
