Highlights

Lumsum Thai Cuisine, a mom-and-pop Thai restaurant at 14870 N. Northsight Blvd., Suite 103, Scottsdale, is the metro's newest kitchen devoted to Isan cuisine — the regional cooking tradition of Northeast Thailand.

Operators Arisa Chakkaw and Thanida Trongprasit are the faces behind the concept, photographed holding dishes inside the dining room for The Arizona Republic's April 15 First Bite feature. The Republic's dining guide named Lumsum one of three new metro Phoenix restaurants to eat at first, alongside Marisco Boys and Four Desserts, in its May 1 roundup.

According to the Yelp listing, the restaurant is open Monday and Wednesday through Friday 11 a.m. to 8 p.m., Saturday noon to 8 p.m., and Sunday 3 to 8 p.m.; Tuesday is closed. The phone number listed is (480) 474-4909.

The Northsight corridor, north of the 101 near Kierland, has seen steady independent-operator activity in recent years; Lumsum adds a regional Thai specialist to a stretch dominated by chain and fast-casual concepts.
