OK, so I talked to IPO and Il Mulino - yes they're closing for some large event. They'll be closed all night. Obviously these things come up, just bad timing.
Il Mulino offered me a reservation at bluezoo - while I really like the restaurant, and love the drinks, pre-marathon food it is not. Post marathon certainly. And all they can guarantee me at this point is some type of pasta special. So thats gonna be a no go.
So I've told the event manager at the restaurant to get me a reservation at either Tutto or Portobello's. I didn't think Via Napoli, but thats another option I should let them know is acceptable. I'd also consider Mama Melrose - I liked it the last time I ate there. Not quite the same caliber as Il Mulino, but very good.
Oh well, time to see how good that famous disney customer service is getting me a reservation for good Italian food 3 weeks out from the marathon. I'll keep everyone informed as to how it goes.
