Emily Ratajkowski Says Jimmy Kimmel's Mom Makes A Bad PB&J

Emily Ratajkowski ain't handin' out any 5 star Yelp ratings for Jimmy Kimmel's mom's peanut butter and jelly sandwiches.

We got Em Rata leaving Amazon's Emmys After-Party at Sunset Tower and asked her if she scored one of 7,000 sandwiches the Emmy host's mom supposedly made for the crowd.

Check it out ... Emily wasn't a fan, but something tells us she's very particular about things.
