Kim and Pete left the upscale Giorgi Baldi restaurant in a Lamborghini SUV.
A source previously told E! News, "He makes her laugh the entire time they are together."
Pete dressed casually in a T-shirt and baseball cap for their night out.
This is one of Kim's first forays into the dating world following her split from Ye, formerly known as Kanye West. Pete sported a pair of jeans from Ksubi.
Kim and Pete officially started dating after the reality star took him to her mom, Kris Jenner's, home in Palm Springs, Calif., an event that a source previously described as a "huge deal."
