Hey! Sorry it's taken me so long to reply to your question re: what cake we went with at Auletto's--I just got back from my honeymoon and we didn't have internet access.
Anyway, we went with the plain pound cake with buttercream frosting (as opposed to fondant). It was so good. They gave us a bunch of cake samples to take home and try after our tasting--heaven

Good luck with your planning!
Sarah
