That actually sounds like a really sweet idea. If you’re open to heading out to Granbury, check out

What made it even better is they do boat rentals, so you can go out on a pontoon before or after dinner. It felt kind of spontaneous but still low-key romantic. Would totally recommend it for a lakeside date vibe.
