No time to catch some hawker foods during a limited-time visit to Singapore? Now, one can have a last chance to do so at Changi Airport before you board your plane. Or more specifically, at the Singapore Food Street at Changi Airport's Terminal 3 in the transit area, i.e. you'd have cleared the immigration lines after checking in.
As all the transit areas in Changi Airport's three terminals are interconnected via travellators and fast Skytrains, it doesn't matter which terminal you're using - getting to Singapore Food Street is a breeze.
I tried Yong Kee's Fried Carrot Cake ("Chai Tow Kway") and Fried Hokkien Prawn Mee, and both were as good as those one finds outside in the hawker centres in the city.
