The restaurant is set with two sushi counters, each seats a maximum 8 people per session.
Saito is fully booked while I was there. They are not even taking reservations until 4/30. Seems like before that its reserved for Four Seasons guests. They open on 3/27.
Lunch is served from 12:00nn – 1:30pm offering around 14 kinds of nigiri with soup for HK1480 +10% service charge per person. Dinner is served at 2 sessions from 6:00pm – 8:00pm and 8:15pm – 10:15pm respectively at HK$3,280 per head + 10% service charge, offering around 6 kinds of appetizers and 10 kinds of nigiri with soup. There may be adjustments based on the daily fresh-catch we receive from Tsukiji Market.
So I guess its slightly less expensive vs Shikon.
