Apples and cherries are the most famous, and real Laiyang pears can't be bought. Only the pears on those trees in Laiyang are the real Laiyang pears. They have all been sent to the central government, and we have never seen them.
Yantai's seafood is also ok, such as prawns and octopus in Bohai Bay. Long island sea cucumber.
Also, foreigners, especially Jiangnan people, all know Changyu's three-whip wine, hehe, it is also a specialty.
