Crazy Dessert Bar in Manhattan?
You might be looking for Room for Dessert, but it's not on Houston; it's on Kenmare, about 4 blocks south of Houston. Or WD-50, whose old dessert chef Sam Mason was somtehing of a genius and is opening a new place in March, on Broome. I don't know if either r4d or wd50 served pineapple vapor, but it's in the realm of possibility. To answer your question, no I don't think it's on Houston, unless Katz's is under new management.
