Worth the wait for Sunday brunch
I like to eat here after my Zumba class nearby. It was just me and a friend but the wait was 30 minutes. Square also seats the counter, so don't sneak up there unless you are called. Seating in general is tight, so get cozy and don't talk about private stuff. Actually this would be a great place to break up with someone... very public.
There are a ton of vegetarian options including jackfruit, Brussels sprout hash, and soy sausage. I like the pancakes best. You can get any pancake as a single if you want to try a few or can't eat a stack.
Also, their espresso beverages and milkshakes are amazing! You should splurge on them if you can.
