You can call a head
No, but as noted in other answers they do offer call ahead which outs your name on the wait list when you leave your house instead of waiting until you arrive.
Call ahead on weekends
No
Call ahead on Friday and Saturday nights
Call ahead
I would advise to call ahead, and get on the list. For clarification, this is not reservation, but it does allow your waiting time to be less. The average waiting time on the weekend around prime-time(6:00pm.) is 2hrs. without call ahead.
No. Just call ahead seating.
Yes
You can call ahead but actual reservations I don't think so.
