I am thinking it's DDP or ADR--so this poster either wants restaurants that don't take the DDP (Swan/Dolphin restaurants) or restaurants you can get into without ADR's (that would probably be any restaurant that is either really off the beaten path or has a lousy reputation. Sometimes you can get into the "hidden gem" restaurants--like the Wave, GFC, Turf Club or Olivia's--without an ADR. For popular restaurants it could happen, but you would be taking a huge gamble.
