Suggestions for First Time Visitor!

Looking for some help on suggestions. Visiting WPB for the first time and wanted to get some info on what you think are must see, eat, walk, try, etc. in the WPB area.

Staying in Lake Worth Beach, but will have a car to share and travel. I don't expect to travel far but if something is worth the drive then we will consider.

Some questions for though:

1. What are your 5 restaurant recommendations?
2. What are the best beach areas?
3. What are some activities to do for a bigger group of adults? (8 people)
4. Are there any rentals worth doing? (Boat/scooters/etc)
5. Romantic date night restaurants/areas?

As always, thanks for taking the time to share feedback! :)
