I had sticky toffee pudding, my husband had salted caramel blondie, and my friend had Butterbeer. All were delicious, although I didn't try the Butterbeer because I can't stand the stuff. I asked for a sample of the chocolate chili, but no samples were being given last night, so I guess I'll have to go back for it.
Even with a TM preview, and not that many people in the area, Florean's by far had the longest line, so I can't imagine what it will be like with many thousands of park guests in the area.
