Live music while you eat and/or drink? Head to a restaurant like The Rustic in Uptown, Sundown at the Granada in Lower Greenville or The Box Garden at Legacy West.
If you or your date is a bit newer to golf, try booking a tee time later in the day. It tends to be less crowded (and can save you some money on your green fee!).
You can go to a college baseball game or go to a Frisco RoughRiders and take advantage of a fun atmosphere with fairly cheap drinks.
I personally love going to Mutts for lunch or spending time there in the afternoon with a cold drink in hand. Also located in Allen, Uptown Dallas, and Fort Worth.
Let me introduce you to the HDW, or the “hot date walks”. Of course you can walk around your neighborhood, but why not elevate the surroundings with a walking trail?
