At the monorail hotels? The Wave or Tambu are fine. I do understand that Mizners at GF will sell some appetizers from Citricos. Haven't tried that yet and it will be great if they do.
Cannot say what the best is because so many are good. Wilderness Lodge's Territory Lounge, the bar at Jiko (I don't mess with Victoria Falls, just go straight to Jiko), Sanaa's bar will be great when I get there, the Tune In Lounge at DHS is a favorite, Yak & Yeti, the Gurgling Suitcase at OKW, Bluezoo, Raglan Road.
