Are reservations recommended for lunch?

you don't have to have reservations but it'd be wise that you do make one. The Waiting could be up to 40 minutes to an hour.

They are recommended, but not necessary. I suppose that depends on what day you go. We went early and wete able to sit wherever we wanted.

If you're willing to eat at the bar, no problem. If you want a window seat on the water, yes.

Yes, but we were able to get in on short notice

Yes.
