I visit Vegas for work and I've been the past 2 weeks.  I've been waiting for Giadas to open for a long while so I immediately tried to book a reservation.  The phone number listed never got me to a live person and when I tried to book online it pushed me out to July.  I thought I would just sit at the bar so I walked over twice and both times was told that I couldn't even walk up and see the place without a reservation.  I will write a new review once I get a chance to try the place.  Not impressed so far.  Give us some direction!!!
