I don’t like bowling as a date, like someone else mentioned, it’s generally not so tznius and doesn’t stimulate conversation. You aren’t doing it together.
I’m thinking nature walks, parks, outdoor rec centers, boardwalk… I once went shooting which was really exciting and started interesting (political?) conversations. Too bad it wasn’t a shidduch date!
And now that the weather is getting really nice go to state fairs! Hike in (populated) areas, or if you want to stay indoors go do a Mystery Room. That gives you stimulating puzzle to solve and creates a team setting where you both have to DO SOMETHING.
What about animal shelters? They always love to have volunteers to walk their dogs and give them some attention, go for it!
Visit a small self-guided museum. I’m thinking of the Ripley’s in Atlantic City. That will give you something to talk about!
If you have to ask strangers what to speak about on your date, you obviously need a setting which will be able to prompt conversation. Don’t do a lounge
