Although it doesn't look like it on the inside, hiring staff is usually a sure sign that a restaurant is close to opening. This sign announcing that District of Pi is hiring is in their window.
They are currently operating a food truck, and some of the jobs (e.g. Mobile Food Truck Cook) are clearly for that; however, many must be for the restaurant (e.g. "Restaurant Managers, Kitchen Manager, Assistant Kitchen Manager, Servers, Bartenders, etc.).
They are having a job fair this weekend, we hope this means they are opening soon!
