Wow! Now I am in Germany for business. I was so lucky that my travel agent was able to get me a First Class ticket on ANA for even less than what it normally would have cost for Business Class. 
So, naturally, I jumped at the opportunity. (BTW, I only fly business class when it is part of the client contract. I can't afford to pay for it myself!) 
This was the first time in my life to fly First Class, so I was very excited. At the same time, though, I thought "Can it really be that different from Business Class?" 
I was pleasantly surprised to find that the answer is "Yes." It's more than simply a "level up." The service was attentive, without being cloying. The food, pictured above, was amazing. Like fine dining in a great restaurant.
Anyway, I hope that this was not a once-in-a-lifetime experience. But I am certainly glad that I was able to enjoy it even once. And I hope it doesn't spoil me from flying in my usual seats in Premium Economy. 
By the way, I can really recommend my travel agent. His name is Vincent. You can contact him at: vincent.dobc@gmail.com
