Here’s some stiff competition for Mission Cantina: Ssäm Bar just launched a delivery program through Caviar, with pork buns, rice cakes, and burritos available during lunchtime. And if you need further motivation to try the next-level Seamless-style start-up, tomorrow through Friday, Caviar will offer 50 percent off all deliveries (not just Ssäm), and new users get their first delivery free.
