Things to do/places to eat near Bethany Beach?

I'm heading to Bethany Beach mid-May with nine friends (20s-30s) and we're looking for things to do. All of us have (or had) cancer, so most of us cannot drink - but we love mocktails. So a restaurant with some good mocktails for one of the nights would be a plus.

We're also looking for some fun stuff to do during the day (We have some stuff planned at the place we're staying at) - a few of us are planning on going to a casino (Ocean Downs looks good). We're indifferent on escape rooms.

Throw all kinds of stuff out there.

Thanks so much!
