Oh that Prison themed restaurant sounds really fun! If you ever do it post about it. Meh I did not buy HSY, I really love playing with my teen but it has the same issue as DU: is not rotational playing friendly. Also DU is huge so even if I regret paying the full price for it, I use many stuff. But HSY is more a limited GP with a lot, lot, lot of stuff (to make it an EP). Sad because the stuff is good and the world is nice.
I will find what type of restaurant can be fun with PJs (maybe a dinner or a breakfast bistro). For now I will keep my little cottage with the PJs option.
I think a PJs kit would be a good idea. Strange that the devs haven't release one.
I loved your anecdote about the slippers (I hope they weren't bunny slippers lol).
