Ideas or tips to entertain someone?

I have a lady coming in from out of town this Saturday and I'm looking for fun ideas to do with her while in town. With this oppressive heat I'm thinking indoor activities but I'd like for them to be "Austin" type experiences. I wouldn't usually reach out to people for ideas like this, but I've been so busy these last few weeks I haven't found time to sit down and plan anything. Hoping I can get some help here. Appreciate any feed back.
