The coffee outlet serves Starbucks. It is called Java Cafe. I was told by several people at NCL that since it is not a Starbucks you can't use the beverage package there. I've asked in a couple of threads in the past month about this and haven't been able to get an answer from someone who has the package and was able to use it. Per a press release over a year ago all ships were supposed to have Starbucks by end of 2022.
Maybe we can get an authoritative answer here!
