I've had mixed results, notably at the R&C. As I approached the desk one evening, I overheard the CM tell a party of 4 that there was no room available or any reservation times either. I told the CM I'd heard what she'd said the bunch in front of me but that I was just a party of one. Next thing I know I'm seated at a table for one, and only one! There was absolutely no room for a second chair. When I told my server that I not only knew where he was from, but had actually lived there, all the other servers came over to chat with me throughout my meal. I had a great time. On the other hand, most of my other "seating for one" attempts that trip failed (though I did have some ADRs that I used).
