I take it it's a mall? Is it related to GrapeVine Mills in Texas as we have been there and it's HUGE. The areas are grouped into "Neighborhoods" so you can find your way round as you would get lost otherwise.

The other one that springs to mind is Potomac Mills just south of Washington DC which is part of the same group and whilst not as big as Grapevine (everything in Texas is bigger) is still HUGE.
