wolfgang pucks cafe wouldn't let us get our desserts to-go. We didn't ask at any other places, but we did ask there and were told no.
The only time they did that to us is when walking up and asking to order a dessert to go. But whenever I've been at a TS resturaunt with reservations, I've always found them very accomodating of taking left-overs/dessert to go. Sometimes, CMs even ask, "Would you like the rest of this in a to-go box?"There is at least one restaurant (Olivia's) that has refused to package desserts to go. So be prepared for things to go either way.
