Joined by a male friend, the couple was tucked away in a corner booth for their 8:30 p.m. dinner at José Andrés’s molecular gastronomy hotspot, The Bazaar.
A fellow diner didn’t spot Berry’s mystery green ring – the actress kept her hands mostly under the table – but noted that she and Martinez kept their PDA to a minimum, adding that they were “acting cute but not overly couple-y.”
Berry, meanwhile, was sipping a “Jalé Berry” cocktail ($16) – made with fresh blackberries, gin, Cointreau and a slice of jalapeño, and named after the actress. The group enjoyed the tapas-style menu, and Berry was seated in between the guys. The dressed-down trio were smiling and laughing a lot, the diner adds, and flying under the radar. – Mussarat Bata
