Is the lack of creme de cassis a blip on the OPs flight or a widespread removal from the onboard bar? I'm perfectly happy to avoid it but the other half will be hoping for a Kir Royale or two onboard in a few weeks.
Burger or something fairly simple on the menu is a good thing; I was in GF before xmas and witnessed a group of 4 or 5 adults grimace at their phones for a couple of minutes before loudly agreeing they were all but one going to order the chicago town pizzas from the kids menu. Which I found mildly amusing but the main point being clearly they were after something straightforward and found nothing to fit that on the 'normal' menu.
