I'm staying at Bellagio in a few days and have booked a table at Picasso.
One question re: the dress code for the restaurant.
The Website says "business casual", rang reservations and they said a Jacket was "optional, but preferred".

We were going to wear smart trousers, shirt and tie, but taking a jacket over just for one meal sounds like a hassle.

Those who have been, what are the majority of the diners wearing, do most people bother with jackets and what have staff attitudes been if you havn't worn a jacket.

cheers!
