"There you go. Ernie's 8:00?"
Ernie's is the name of the restaurant where Chandler Bing and Susie Moss took their first date during the episode The One After The Superbowl, Part 2.
The place is never seen but mentioned during their first encounter in the set of the movie Outbreak 2: The Virus Takes Manhattan. Presumably, after the date at Ernie's, they ended up at Sussie's house because Chandler said that he met the perfect woman, because when they were on Susie's couch she said "Did you ever want to do it in an elevator'?'"
