Well, it's a three month pop up thing, not a permanent structure, so I'm not sure what was to be expected. I have seen temporary bars in the past in other lounges. I'd say that this strikes me as on par with the more polished attempts (regardless of whether it is to one's taste or not, but it's certainly not out of line with plenty of designers/decorators' stuff I have seen of late).

In some other cases, like the LH pop up Campari bar, whilst I really like the drink, the installation itself was more like the sort of cart you get when brands want to give out free samples on the street. This is despite the duration of the installation being similar to this Whispering Angel bar.
