I think Descending has given a definitive answer (thank you!); I will just add that in my experience this break often occurs around rows 67/68, so you might find you get served reasonably efficiently there.
Or just order a SPML to get served a little sooner, although your drinks will take the same time and your meal may well not be as tasty or balanced as a the normal one.
On the flip side, the SPML tray will be on your table all that while longer
