If there is, I haven't found it yet. Many smaller ones have closed.
I go to Dallas North Aquarium on Trinity Mills, just west of Midway, which is a nice store but not too exceptional.
Dallas World Aquarium has just opened a new wing with bull sharks. Their octo exhibit was not very good, but they have some nice other exhibits. The Aquarium at Fair Park has a GPO that they feature - haven't visited it yet.
Where do you live when you're not visiting Dallas?
