Do we have to make a reservation or can we just walk in also because we don't know if we are going we have stuff to do before we do anything

Make a reservation to gareentee you get in but you can always cancel

Yes you need reservations

Reservations should be made. If you dont there is a high probability of waiting a while to get seated

Reservations are recommended as they are often too full for walk-ins.

You want to make a reservation. You wait till last minute they'll be full up.

Our party is only for three people

Reservations are highly recommended. It is a very busy place.

Reservations are highly advisable, they might not be able to accommodate you... the earlier you go the better chances you have of getting seated without a reservation if your party is not too large.
