The 29-year-old actress, who recently paired up with Byrdie for a feature on how to style her new haircut, wore her short tresses wavy and loose for her date with French at The Village restaurant.
A day before the outing, Tisdale made headlines for a Twitter exchange she had with former High School Musical co-star Zac Efron.
"@ZacEfron ur the sweetest! Always remembering my birthday even on vacation :)," she tweeted at the actor after he congratulated her on her July 2 birthday.
Tisdale and French announced their engagement in August 2013 after eight months of dating.
