Umami Burger with Ashton Kutcher, that's what Mila Kunis had in her agenda on April 12, Saturday night while in one of her pregnancy cravings. The newly-pregnant actress craved for the Umami Burger and she and fiancé Ashton Kutcher stopped for the famous Umami Burger in Burbank during for a quick date night meal.

While pregnant Mila had a Cali Burger, Ashton opted for a Royale Burger, which is a beef patty topped with braised short rib, roasted garlic aioli, and house-made truffle cheese. Kutcher paired his Royale Burger with an Allagash White beer, a source says. Meanwhile, Kunis had ice water with lemon as her beverage.

The source said that as the couple ate, they looked to be in good spirits, laughing and chatting with each other while Mila satisfied her Umami Burger cravings.

So what exactly is in the famous Umami Burger so delicious that makes even a star like Mila Kunis crave for it in the middle of the night?

The Umami Burger which Mila craved for that night is the Cali Burer, which is made with butter lettuce, slow roasted tomato, house spread, house-made American cheese and caramelized onions.

An Umami burger is filled with secret ingredients of umami properties, a flavor that is out of the traditionally accepted tastes of salty, sweet, bitter, and sour.

The delicious Umami Burger has several locations in the US including California, Florida, New York, and Nevada. The Umami Burger branch visited by A-list stars Mila Kunis and Ashton Kutcher was in Riverside Drive of Burbank, California.
