Residents of Brooklyn. Anyone remember Garfield's Cafeteria?

In the 60's my ,mother used to take me there,to meet my grandfather for lunch. It was on the corner of Flatbush and Church, as I recall. Close to Erasmus High, and the Rialto Theater. Garfield's was this huge art-deco cafeteria, two to three stories tall. with hundreds of communal tables. Buffet only, always jammed. The food was great! Garfield's doesn't exist anymore. I'd like to know when it was built and by whom, and anything else you'd like to add. Googling didn't help. I know you can! Thanks for the memories.
