I do recognize that menu! Did you try the lobster salad? I'm happy to see that BA has added a hot dish (the quiche) to its afternoon tea offerings. I also expect I'll be in the new menu cycle for my LHR-MIA flight next week.
Off to the Big Apple in style... so far as I know, that can only mean CX First Class or a room on The Canadian to Toronto followed by a flight down to NYC. Happy travels regardless!
