Thanks Amata, I was thinking of Sable or the lobby at the Peninsula hotel too. It's strange, many years ago, the only places that serve Brunch are hotels and now if you want a weekend lunch place (and not brunch), you have to go back to hotels again.
NFriday,anywhere in the city is fine (just not suburbs); so looking to spend what Naha or Blackbird will charge for a weekday lunch (unfortunately neither one opens on Saturday for lunch). We don't mind ethnic at all but I haven't found place that serve Saturday lunch that is similar to Naha or Blackbird type of food quality and atmostphere.
