My first date would be more about getting to know each other. Somewhere we could walk and talk example like the museum. Then maybe have dinner after. I would want to just enjoy that time with that special person.
I don't really like eating on first dates, so my idea of a first date would be a museum or an art gallery, basically somewhere more intimate where we can get to know each other and talk without a bunch of interruptions.
Well first date for me would have to be something like going to the museum, or museum hopping. Even maybe hiking. And a nice lunch or dinner after depends on the time.
But I'm always open to other ideas :)
