It includes the airline’s signature ramen or curry and rice dish, pasta, sandwiches, salads and ice cream. These can be ordered any time after the main meal service.

After dinner, ANA does food a bit differently than many other airlines. Rather than having a defined breakfast or lunch menu before landing, you can simply order anything you'd like – at any time.

The airline has a special Brazilian blend made for the airline as well as a variety of teas including iced green tea. ANA’s bespoke citrus and honey drink is another non-alcoholic beverage to sample on board.

There are two lounges, the ANA Lounge and the Blue Lounge, which are open to all passengers on payment of the entry fee and with free access for passengers holding business class tickets with affiliated airlines, some members of frequent flyer programs and holders of associated lounge club cards.

But ANA didn't sacrifice privacy in making The Room seats so big: Yes, there are privacy doors on each suite. After takeoff, you can pop out a pair of panels with a sustained push of two buttons.

ANA’s inflight service is incredibly friendly, but also very Japanese in its service delivery with everything served with formality and precision. Passengers can choose between Western cuisine and Japanese set menus with dishes designed by a team of ANA “connoisseur” chefs.

Each seat has a large side table, storage area for bottled water or small items, power and USB outlets, a dining table that folds out and storage areas near the armrest.

A glass of champagne and a dish of those excellent Japanese pickles made it the perfect meal before arriving in Tokyo.

And while the service and dining onboard this ANA business class flight was all good, even great, it didn't quite meet the perfection of the suite itself.

Beverage refills are not very proactive, either, but the problem is somewhat alleviated by a push of the call button – and the crew will be in front of you in usually less than 30 seconds.

This is then followed by the beverage of your choice with an amuse bouche and warm towels, but with such a large business class cabin, service can take time.

Throughout the flight, small bites were available, ranging from the corn soup as mentioned above to Japanese udon noodles garnished with mixed vegetable and shrimp tempura. One highlight is ANA's curry here and steamed rice.

You can adjust your seat from a panel in the side console, and it's incredibly customizable. Not only is there a slider at the top to recline or sit back up to your heart's content in addition to some preset buttons for lie-flat, upright, and dining, but you can also move your seat forward and backward – perfect for when you need to slide out in the middle of meal service. That's something far too many airlines miss.
