Best Italian rum cake in the city?
Well, I bought one just before your response arrived. Ended up doing a amaretto cake from Villabate Alba. The cream was amaretto, and it had amaretti cookies around the outside, while the actual cake had rum in it.
Not overly rummy, but a tasty cake nonetheless. I don't know if my wife was looking for something more akin to a baba rhum, but she enjoyed it. It's worth noting that the decoration of this 12" cake, which cost all of $28, was absolutely beautiful.
