The Grove Street PATH station is closer to central Jersey City where many restaurants are located. There's a great farmer's market here in the summer time.
If u get the path refill card and fill it with 20 bucks. It's only 2 bucks a ride compared to 2.75. It's worth the 5 dollar investment to purchase the refill card.
For Andriod users, I suggest downloading the SchedNYC app. It's mainly a schedule app for the NYC Subway but now it includes PATH schedules. Very nice and useful app IMHO.
Inquire with you State government officials why a public utility like PA doesn't have to recognize federal Americans with Disabilites laws. No elevator or escalator access in the newer Marin entry.
