Was on DXB-LAX a couple days ago on the new bar design (with tables). Basically they allow one table to be occupied by a group of max 2ish people while they have beverages or meals there... I had to wait quite a while for a table to open up - was pretty much only the last 2 hours of flight. The bar itself is closed but they keep your wines, etc nearby for refills and you can order anything that's on offer for your cabin.
