Rhino's Chili was a popular restaurant in Gotham City.
The restaurant was one of Dana Tan's favorites, and she and Terry McGinnis were set to go on a date there. Unfortunately, Terry was forced to cancel at the last minute without telling Dana when he had to deal with Mad Stan as Batman.
When Dana was abducted by Patrick, who lived underground, he tried to appease her by getting her some chili from the restaurant. He went with his giant rats to get the kind she liked, which sent the customers running out of the restaurant in absolute horror and disgust. Batman comforted the rats and tried to fight them, but was beaten, although he did hear Patrick mention Dana, and managed to follow him to his hideout from there.
