As a 2022 update..

Food offerings are still very, very limited.
Drinks are ok (soft, beer, wine and some spirits).

We are in CE, so no issue with access - although there is a prominent sign saying 'no frequent flyer benefits' - so not sure if you were gold/ silver etc you would get in.

it's quite a nice space for somewhere quiet to wait - there is maybe 50 seats in total - so capacity may be an issue (& is maybe why the access appear limited)
