Do u ever get a seat on the weekend if u don't make a reservation for a party of 6 possibly?

There's no way you'll get a seat for 6 on a weekend without a reservation.

Very busy on weekend....I wouldn't​ advise you to just go in on a weekend. I did that and waited an hour and a half for a seat. Very busy and popular place

You will likely need a reservation

Definitely not

Probably not, unless you go super early or super late
