The short cake is so awesome that I can't imagine having regular cake too! I've heard if you call ahead, then can make something special, but I too don't know when they'd bring it out. The servers are running around so much and clearing tables and bringing food out that I don't know if they'd have time. I'm sure they'd make time, but I would just stick with the shortcake.
Man...now I'm craving some strawberry shortcake...
