有無人去過深圳機塲? 知唔知有無野行 or 食?

Yes. But you don't expect like HK airport. They have McDonalds, KFC, Starbucks... plus a few local restaurants/fast food shops & a few souvenir shops.
Not suggest you go unless you have business trips fly from Shenzhen airport.
In case you still want to take a look, they have shuttle bus from Science Centre MTR station costing RMB 20/person operating from 6:20 am till 9:00 pm.
Hope this helps.

你是指入閘前定入閘後?
深圳寶安機場分A,B兩區很大, 入閘前也有一點商舖,但沒有甚麼特別東西買你見門口就沒興趣入去商舖內看, 入閘後有有免稅店同是見門口就沒興趣入去那種.
食野方面
有麥當故奴, KFC, 大家樂, 中國式coffee shop(很土), 還有其他食店.

如果是機場對面(大鐘那邊), 全部是普通市民住的地方沒有商場等等, 只有畜當地小店, 從機場行過去也要10分鐘

入閘前, 就係當地食肆, 或McD記,KFC, 當地食肆啲嘢好難食, 入閘後有免稅店, 但不是太多, 通常如果不是好必要, 都唔會光顧佢地。服務又差。
