The former couple, who have decided to be friends after reuniting for the first time in two years, headed to the popular Sheesh restaurant in Chigwell, Essex, on Tuesday evening (1 July).
Arg and Lydia were all smiles in the snap - and it looks like they had quite a feast too! Captioning the photo, Lydia said: "Lovely bit of dinner after filming @SheeshChigwell with @RealJamesArgent. Now I can't move on the sofa #FoodComa."
Sheesh also posted a similar photo on their Twitter account, saying: "Nice to see these 2 back together. (Just Friends?)."
Arg and Lydia have been spending lots of time together recently since reuniting in Marbella last month. Over the weekend, Arg took Lydia to a Stevie Wonder gig and the pair looked close as they posed together for a selfie.
During Sunday's episode (29 June), Lydia accepted the invitation to the gig, but she admitted to Arg that she thought their friendship was moving too fast.
"I kind of feel like its gone from zero to 100 in two weeks," the Bella Sorella boutique owner explained. "I feel like you're suffocating me at bit. I do really want us to be friends, but it's still early days. You just need to cool off a little bit. You're moving to fast, but cool down."
In sneak peek pictures from tonight's show (2 July), we see Arg and Lydia spend more time together as they go out for drinks, but she makes it clear that she just wants to be friends. Will Arg struggle to respect Lydia's decision?!
TOWIE continues tonight (Wednesday 2 July) at 10pm on ITV2.
