{blackbabes} Beyoncé & Jay Z's Day in Boston: Champagne & Shopping Sans Blue Ivy

No matter the weather, Beyoncé and Jay Z enjoy their time together.

Despite some rain on Tuesday, the Magna Carta Holy Grail rapper and his wife shared a romantic lunch in Boston – the latest stop on Beyoncé's The Mrs. Carter Show World Tour.

The couple – sans daughter Blue Ivy – sat side by side as they dined at Sam's at Louis on the South Boston Waterfront.

To complement the French-American bistro's fare, they ordered a bottle of Champagne on ice, an onlooker tells PEOPLE.

After their quick bite on Fan Pier, the couple visited Louis Boston, a high-end boutique for men and women that was temporarily shut down so the pair could shop in private.

Following their shopping excursion, the duo took off in an SUV with two bodyguards in tow, so Beyoncé could prepare for her live show at the TD Garden that night.

Beyoncé must have enjoyed her lunch, because during her concert she announced to the crowd, "How you doing Boston? You guys have good food!" says another source.
