I ate here around 11am on a weekday. I got in and sat down no bother at all, but it was busy when I left just after midday.
I had eggs with home fries and pork sausage followed by danish pancakes. It was difficult to finish, but really tasty. Ther service was fast and friendly. I was never without coffee or water and the food came out freakisly fast!
The prices were reasonable, I think my cheque was for less than $20 including a tip (and I'm not a tight person!). It's just up from the Brooklyn Museum and Prospect Park and the Botanic Subway station is about a 5 minute walk away. For me it was worth the trip, I'll probably go again before I leave NYC.
