Kung Fu shows up on HGH’s food listings but not maps.
ChinaAirlineTravel lists Kung Fu as a Chinese fast-food option at Hangzhou Xiaoshan, grouped with Old Uncle and Read Brewed Tea, but doesn’t pin a terminal or gate. You’re flying from T3, so assume it’s on the domestic side and be ready to pivot if you don’t see the yellow “Kungfu” brand logo after security.
Signage at HGH still lags the actual tenant list, so a place can appear on the airport’s restaurant page while its exact spot in T3 stays unclear. If Kung Fu is running here, expect a basic counter setup with trays, similar to what you see in Chinese railway stations: rice, meat, veg, all under heat lamps. It reads fast food, not a sit‑down meal.
The chain in other cities sells single-plate combos in the roughly 30–45 RMB range, so budget about that for a main plus a drink. That prices it under a full-service restaurant in Hangzhou but above a packet of instant noodles from a T3 convenience store cooler. If you’re trying to keep a layover under 50 RMB for food, Kung Fu fits that plan.
Hours at HGH aren’t posted for Kung Fu specifically, but domestic-side fast food in China usually runs from around the first departure push (about 06:00) until the last bank of flights (often after 22:00). If you’re on a very late arrival into T3, don’t count on it being open; grab something on the plane or from a vending machine near your gate instead.
One practical move: as soon as you enter the T3 departures hall, ask the information desk in Chinese or with a map screenshot for “功夫快餐 Kungfu.” If they shrug, don’t burn twenty minutes roaming: head for clearly marked chains like Old Uncle or a basic noodle shop and eat within sight of your T3 gate.
