This was my guess, but when I said "sales were low" on Twitter I was attacked.
I ate there at dinner time on my vacation a couple weeks ago and it was dead, absolutely NO ONE in line ahead of us. Compare that to when I dine at Leaky Cauldron or Satuli Canteen and they seat with me with another family or outside due to lack of available tables and I'd say it's not doing as well as it could be... ESPECIALLY for a brand new billion dollar land.
