QA 787-8 Dreamliner is equip with a bar in the middle of the cabin, in between the L2 and R2 doors. In my prior experiences onboard QA snacks and beverages/champagne (served) were readily available mid flight, and were not uncommon on shorter routes. Presumably, one could self-serve or be served, to passenger preference. On this flight, the bars were empty, perhaps Covid restrictions?
