I repeat, I'm no real estate expert, but...

... it seems to me that if you're going to start a retail business in Flower Mound, you're going to want to that business along FM2499. This goes doubly true for restaurants (see LaNella post below). There are other corners in town where you have a fighting chance (Morriss and 407, and perhaps soon Morriss and 3040), but if I were trying to be seen, I'd want to be on FM2499. Nothing else would come close.
