LEGO CITY Undercover

After finishing chapter 4 & opening the bridge to more of the city, go past the Pagoda (Chinatown) section & you'll hit the Bright Lights Plaza (NY Times Square). In between the roads is a mall section, with a car ramp in the middle. You'll find a dynamite vending machine shortly after the ramp, carry it around to the middle right of the building & blow up the entrance to the Lego store. Then once in there, simply destroy the lego boxes & then build the Lego sets from the destroyed boxes. Very easy :)
