Cali chain Umami Burger will open its first non-CA location in South Beach in Spring 2013 (1080 Alton Road), a mere 8 blocks away from Shake Shack. The chain is on a massive expansion tear with several new locations opened in Cali this year and one planned for NYC in March 2013.
And last but not least, Miami-based eatery Yardbird (helmed by Top Chef alum Jeff McInnis) is planning to expand to NYC in 2013, according to Grub Street, who reports it will feature the same Southern-inspired comfort food of the SoBe original.
