I haven't done it but I want to try the make your own icecream sandwiches at MK bakery. On my list for this trip.
And apparently at POFQ they have some kind of pastry similar to a doughnut or cinnamon stick that's very good. We are also going to try this out this trip.
I second the WP cafe in DtD, great food. Really liked the Flame tree at AK.
We also liked the Earl of Sandwich at DtD.
Any CS suggestions for HS?
