I'm not sure if Suntory (which, I plugged in the OP to this thread last year) still exists, but if it does, check it out. The HSBC building was Mori's first project in Lujiazui (subsequently trumped by the WFC in 2008), and F500 Japanese tenants were a crucial part of the plan. Suntory was awarded the contract to provide F&B services on the top floor (split between a restaurant and lounge). Unlike the family style venues in Changning, chains like 大鱼, or fusion restaurants like Hatsune or Shintori, the MO was high quality Japanese food from the get go.
