My wife and I just got back from a 2 week trip from the US to South Africa and flew ET. The wines on board are distinctly better that what I would normally get on UA or AA (the vast bulk of my business/first experiences on both carriers is pre-pandemic). The highlights for me were a Spanish Red blend and a South African Pinotage. The Ethiopian coffee is both strong and tasty.

The food IMO is some sort of fusion between Western Europe/North America and Ethiopia. Most of the Western meals are palatable, although I found one of the beef dishes over cooked and chewy. There was an Ethiopian lamb stew that I found very tasty. Many flights have a section title "The Ethiopian National Dish". Personally, I like it. But I know of many who do not. Many of the snack option on the longer flights have egg rolls, samosas, breaded chicken and/or fish that look like they came out of a bag of froze starters from a cheaper food service.

My wife took some exception to the food as she felt it was a bit over seasoned (chiles). But I grew up in south-central Texas and I grew up eating food much. much spicier than what we were served.

As always, YMMV.
