Why people love Dig Inn, the healthy restaurant chain that just raised another $30 million from investors

Dig Inn, a 15-restaurant chain with locations in New York and Boston, is already a hit with healthy eaters. In both cities, you're bound to see crowds lined up to get salads or market plates any given day of the week.

With an average meal price of $10 and a focus on produce sourced from local farms, the chain aims to make simple, high-quality food available at a relatively affordable price. 

Now Dig Inn has raised an additional $30 million in a Series D funding round led by AVALT. Other contributors to the round (its largest to date) include Monogram Capital Partners and former Outback Steakhouse CEO Bill Allen.

The company had previously raised $21.5 million in earlier rounds of funding. 

Dig Inn will use the new investment to launch more restaurants, open a culinary training school that's free for employees, hire more management, and finance its farm in upstate New York, which will deliver its first harvest in early summer 2107. The chain also plans to open 13 to 15 more locations in New York, Massachusetts, and a third to-be-determined state by 2019, founder and CEO Adam Eskin tells Business Insider.

Here's what it's like to eat there.
