I would look into the Galleria definately. For the younger ones there is an American girl store/bistro and an ice skating rink (after competing of course!). For the older ones there are a ton of shops anywhere from H&M to Zara to Betsey Johnson to Louis Vitton and a wide range of restaurants. I have also heard good things about the Dallas aquarium as well, but y'all have some fantastic aqariums such as the Monterrey Bay Aqarium or the Aqarium of the Pacific out in Cali so I'm not sure if thats something y'all would want to do in Dallas. The zoo is alright, but a bit small in my opinion compared to the Fort Worth one on the other side of the metroplex, and again nothing like the San Diego Zoo or anything. If your kids would be into a themed dinner then for the 15/16+ up kids I would reccomend richard's last resort but make reservations and be prepared for it to be very busy...... Usually more entertaining in a big group as well. Also it has to be earlier in the evening prior to 10pm i believe it is, as thats when the drinks start rolling out and the bachelorette parties start rolling in. Medieval times is fun to do for a themed birthday dinner/show with younger kids as well if you don't have one by you.
