We were only in Economy Plus so United doesn’t offer provide food service, but they do offer a choice of snack. My order is always a non-flavored seltzer water, cup with no ice (don’t want water/ice/coffee/tea coming from those nasty water tanks on board) and a Stroopwafel. I placed my Stroopwafel on top of of my cup of seltzer like you would with coffee. Of course, coffee would help warm it up and make the Stroopwafel just a bit better, but putting it on above the seltzer made it colder and arguably made it just a slightly worse. But even a slightly cool Stroopwafel is better than none! Also, sorry no bathroom picture to go along with this dining experience, but you can pretty much picture what it was like anyway.
