How fun!!!
The Shops of Legacy has great places to shop, dine, wine, etc. Cru Bar is fun and a great people watching place to be. Martini Park is fun later in the evening. Hop a little North to Club Nylo (new hotel on Headquarters/Preston) and there is Loft 610 at the tollway and 121.
Montgomery Farms in Allen has a very nice shopping area opening with dining, which is fun as well. The location is Bethany/75.
Northpark Mall is a classic to take people shopping and people watching. La Madeline is a great little place to get a bite to eat. Stonebriar Mall is a good shopping mall as well.
I'm sure you will have a great time.. Enjoy!
