I had both the Halibut and the Hamburger Sphere on FRA-SFO last week. The halibut was so fishy/off in taste that I couldn't finish it. I think I'll have to stop ordering the fish post-catering downgrade as it's really not a protein that has been figured out with the one temperature to rule them all preparation. In general, I'm finding that only the chicken in liquid prep survives this step of prep towards offering nutritional pucks in lieu of a meal that is the next eventual downgrade. Unfortunately chicken in liquid (ginseng/broth/coconut milk/etc.) wasn't available on this particular flight.
The hamburger sphere was weird but I somewhat enjoyed it. I'd love to meet the person that invented this feat of science. I may have been delirious after the long ride.
It doesn't seem like the wine program matches the menu or any direction these days. A random selection of cheap wines was offered on my flight and the menu offerings were not available. The FA's were reluctant to show or mention which wines they had, instead offering the varietal with no other details. I shouldn't have bothered them with the question, I suppose.
