What's in the "box" behind the R Bar on Grandeur?

Looking at booking on Grandeur of the seas deck 4 but am wondering what's in the "box" on the deck plan behind the R Bar? Is that crew area that will make the rooms surrounding it noisy?

TIA

I’m wondering what’s the box under that too on 3rd floor

If I am not mistaken, it is a supply room for the bar. I have seen bar tenders go there and come back with different drinks.

We had the first OV cabin in the hall after the bar and never heard any noise. Sorry this would not help if you have an inside cabin.

area to make drinks sink fridg etc

Yep, walk in fridge, dishwasher, etc. Back bar.
