What's the best time of day to come here?

I went on a Sunday at around 2pm and there was a 90 minute wait but apparently that's the busiest time to go.

Any time I have gone that WAS NOT a holiday was fine ... i been there mornings, afternoons, and late nights they are open till 12am, but you can only get waffles and some breakfast stuff till 5pm and not a minute past ... unfortunately Can only sit parts of less than 8

Can't say for certain but went for brunch at 11:00 and got a table immediately.
