I was really disappointed with SQ PE - the seats I did not find comfortable, something is not right with the footrest and lumber support combination. I did book the cook and they do not serve any drinks with it - you have to wait till they deliver all the special meals in Y until the drinks start, by which time you have lost interest in having wine with a meal.
I really feel I would have been better off paying extra $ or KF miles for an exit row seat in Y - I tend to think that would be more comfortable...
