Reston Town Center is really grown up. As locals, we've been here for the Thanksgiving parades, the 5k, the bike races. This year, we saw them put up the christmas tree and take it down, the 4 year old is learning to ice skate, and we consider it our downtown.
In the evenings, there are a lot of well-heeled professionals and teenagers wandering about spending more on dinner than I could afford, but it still a place to see and be seen any weekend. That's why we like it more early in the morning.
There are always events here to go see, art events, beer drinking events, holiday festivals and more. It's a great place.
