Bestco is just another T&T supermarket.... I did not get to see the place, only the food court.
The food court is quite disappointing as compare to other supermarkets. Even though the prices are cheaper than T&T, the food there is below average. The sushi and dim sum is disgusting much like that supermarket, the chicken/pork buns are somewhat decent and the rest like chow mein and other cafeteria-style meals served there are nothing special.
The place wasn't as dirty that I thought it would be regardless of it being new.
Although other things like drinks are cheap! They happen to have bottles of lemon tea, three for a dollar!
As a recently opened supermarket, its quite nice for people who don't have to go up north to T&T and a even better option than that small and cramped grocery store in the mall across from there.
