35 baht for small and 70 baht for big

Small - half mango
Big - whole mango

Cheapest Mango Sticky Rice that I’ve had in central Bangkok (in an AC place). Food at Pier 21 is generally similar to the pricing you get for street foods (sometimes cheaper) but you get to enjoy it in an air conditioned environment.

Would definitely recommend people visiting Terminal 21 to check out Pier 21 Foodcourt for their wide variety of food.
