The two friends were seen dining at the Commodore in Williamsburg, Brooklyn, on Sunday night. Lawrence, 25, and Ansari, 32, had a corner of the bar reserved just for them, where they ordered food and laughed together.
"They looked friendly and were showing each other stuff on their iPhones and chatting and laughing," an onlooker tells PEOPLE. "They tried lots of different food and looked like they had a lot of fun. They looked like really good friends."

The pair shared a bottle of wine while dining on a selection of the chic dive bar's famous comfort foods – nachos, mac 'n' cheese, a fried chicken plate and a sandwich for Lawrence. The actress was seen dunking her sandwich into a big pile of ketchup while she ate and later asked the bartender to take a photo of her an Ansari on her phone.
The Valentine's Day date appeared to be friendly, with Lawrence animatedly talking to the Master of None comedian and throwing her head back and laughing.
The pair's friendship is nothing new. Lawrence was seen giving Ansari a piggyback ride when they left a Saturday Night Live aterparty in October. (Their mutual friend Amy Schumer had served as host.) The duo and Schumer also hung out in October when the comedians' touring schedules overlapped with Lawrence's filming in Atlanta, where she was working on a Passengers with Ansari's former Parks and Recreation costar, Chris Pratt. The group (sans Pratt) also spent Thanksgiving together.
Ansari was most recently linked to chef Courtney McBroom, although the pair reportedly split in January, according to New York Daily News. Lawrence previously dated Coldplay frontman Chris Martin, but the pair broke up in August.
