For a meal on the train, don't miss the Fencihu lunch box (奮起湖便當 fencihu biendang), which has a deep-fried cutlet, Taiwanese sausage and a selection of mountain veggies on rice. Vendors come onto the train to sell them at Fencihu station (NTD100 a pop).
Stalls selling noodles, rice dishes and basic street food can be found at the Alishan main square, at Jhushan and the Jhoushen Temple.
While you are waiting for the sun to rise, a hot drink from the vendor will warm your hands. Also try the egg crepe, scallion pancakes and French toast. Hot Clear soup with blood rice cake is also available. Hot Sakura flavoured honey in the early morning is great too.
