I just flew DTW-ICN-DTW in Delta One.

Somewhat disappointed that the meal is served all at once. One purser offered the meal to be served one dish at a time or expedited meal service. If you chose the former he then announced that since the whole Delta One cabin is having expedited meal service I would have to wait until everyone was served.

Just seems that on a 12-14 hour flight leaving mid-day you would have time to serve the main meal slowly without rushing.
