Atop the kitschy but cool Jumbo Kingdom floating restaurant complex in Aberdeen, this new alfresco spot—once the staff's mah-jongg parlor—is a surprisingly stylish place for cocktails. It's worth staying on board for the sushi bar. Daily for lunch and dinner. $$-$$$. Most major credit cards. Top Floor, Jumbo Kingdom, Shum Wan Pier Drive, Wong Chuk Hang, Aberdeen, Hong Kong.
