For a weekend, I'd recommend it. Twas very busy and packed when I went. During a weekend brunch.
Mondays or Tuesdays they are not as busy so maybe you could get a table but to be on the safe side is better to book otherwise you would have to wait for a table, they don't ask for card details or money in advance.
I've walked in before but definitely suggest a reservation
Walk-ins are welcome, but with a short wait for sitting.
