The United Polaris Lounge at Chicago O'Hare (ORD) isn't my favorite, but honestly, it worked. And the Polaris Dining Room is a nice upgrade over the buffet, although I just barely had time to enjoy my meal there.
Onboard the 787 to Frankfurt, the improved-as-of-June-1st menu was in full effect. The main course is improved, the salad is better but still some weird-*ss ideas for a salad, and the ice cream sundaes are unfortunately pre-made so no customization. At least it was nice that my upgrade went through and I was able to lie-flat for some proper sleep across the Atlantic.
