  Salisterra — research source

  Salisterra replaced Cafe Gray Deluxe on the 49th floor and opened in mid-April 2021; Michelin Guide's 14 April 2021 article says it 'has officially opened', so the opening was on or before 14 April. One search summary mentioned 17 April but could not be verified; the upper-house hotel itself opened in 2009 (not this restaurant). Estimated: 2021-04 is a best estimate and 2021-04-30 is used only as a period-end sorting date, not a confirmed opening day.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
