It would be best to call and see if they can accommodate a large group. If they can,it's well worth it!
This past week they replaced the front parking spots with picnic tables, so now that the weather has warmed up they have more tables that can accommodate a group that large. Otherwise they don't take reservations, so best bet would be to go before or after the busiest times. Good news is service is pretty speedy.
I didn't know they took reservations.
I would call the day before and see of they can make any accomdation to have the 7 people sitting together.
Maybe, I'm not really sure about that. They have a website that may provide that information better than I could. My apologies.
