Earlier should be better, but use the Yelp waitlist to improve your chances of getting a table.
I'm not sure either, we've gone in the evenings as well as for brunch on Saturday, but never at 8am. As that's when it opens there may be a small line but I would guess not too bad. Call them and ask, they can usually give you a good idea of their wait times!
I'm so sorry I'm not sure about that. I went there on Friday I had to wait 45 minutes 😩
