I found a better alternative to Chipotle in New York City - and it could be expanding soon

But in New York City, it may have some competition.

Dos Toros, founded in 2009 by brothers Leo and Oliver Kremer, is looking to carve out a chunk of the market.

The NYC chain is self-funded - no outside investors or nest eggs, just a business loan and family and friends- and is expected to earn $20 million this year.

And considering its popularity, the brothers are looking to expand elsewhere as soon as possible. "We can open five a year for the next five years, and move to multiple cities," Leo recently told Entrepreneur.

With nine locations in Brooklyn and Manhattan - one just opened its doors in the Financial District - and plans to saturate Midtown, Dos Toros seems unstoppable.

I decided to head to the nearest one to see why this local chain is exploding, and to find out if it can survive elsewhere in a pretty competitive Mexican fast-casual market.
