On and off since their initial split
in March, Eva Longoria
and Eduardo Cruz recently stopped by Zuma Miami, where they met up for a brief lunch.
But the rocky pair seemed anything but lovey-dovey during the outing.
"They had little to no interaction at all with each other," an onlooker tells PEOPLE. "The lunch was far from romantic."
But still, they managed to share their dishes, which included yellowtail sashimi, a spicy yellowtail roll, shiitake mushroom and sea bass sashimi.
Her relationship with Cruz aside, the source says Longoria, who kept her sunglasses on the whole time, was "very cordial to the staff." – Dahvi Shira
