There's a new burger, fries and shakes joint in JP after Texas-based MOOYAH opened its first Boston franchise this week in Jackson Square. “We are fresh, never-frozen burgers, grilled or fried chicken salads, sweet potato fries, hand-cut French fries, milkshakes, turkey burgers, lean green options and more,” said Jay Hummer, Development Agent for MOOYAH Burgers, Fries & Shakes, to Jamaica Plain News earlier this year. And if you like shakes, MOOYAH is the place for you. They offer a variety of milkshakes including: Hershey’s Chocolate, Vanilla, Cookie Dough, Reese’s PB Cups, Mint Chocolate Chip, Oreo, M&M’s, Banana, Strawberry and Strawberry Banana. “We’re excited for the [JP] location due to the residents and T riders, and the redevelopment that has brought more life to the area,” said Hummer.
