Do i need to make reservations for6 people?

I've never made reservations. I usually sit in the bar. It depends what night of the week you plan on going and how long you're willing to wait. Be safe, make the reservation.

Always better to reserve....app or call.

No, but I always use the app and "get in line" before I get there. Less wait once you arrive.

I would

You can call ahead or use their app to reserve

Don't see a reason. Outside seating there is fun as well

For 6 you can probably just walk in. It may take a few minutes but no need for a reservation.
