Just a few weeks after Klay Healthy Indian Eats closed its doors at Rockville’s Traville Village Shopping Center, another Indian restaurant has taken its place. The newcomer is Yaar Spice, a full-service eatery specializing in northern Indian cuisine with lots of vegetarian options. Manager Maulin Barot says he hopes to add live music, deejays, karaoke parties and a late-night bar in the months to come. Yaar is the fourth Indian restaurant to operate in this space on Traville Gateway Drive. The first was Aladdin Indian Kitchen; next was The Bukhara; then the fast-casual Klay, which lasted almost three years. Will the fourth time be the charm?
