This is a really broad question. Lot's to do depending on what you like from Top Golf to the Nasher Sculpture Center. Can you give more details on what you're looking for? Restaurants, activities, museums, outdoors, indoors, etc.
Beginning in May, the Nasher is starting back up their "Midnight at the Nasher". It is a great date option that the wife and I really enjoy. Typically, they have a band play and then show a popular movie on a Friday night. It is a lot of fun.
