Highline park
Just went out recently and was gonna go there but it closes early still. Not sure when the schedule changes. Also, while i do really like going there on dates, ive found that there are usually untznius women there. Even if u aren’t makpid, it can be distracting and take away from ur interest in ur date.
Theres a starbucks my friend told me about by one of the entrances, real convenient to sit down in before or get a bottle of water.
