Delicious food! I thought my first leg from SFO to Taipei was good, but this second from Taipei to Sapporo was even better. I liked the configuration of the plane 2 x 3 x 2. Although I wish it was made clear that folks needed to have their seats up during meal times. I had to remind the individual in front of me each time, which was awkward.
