This underrated casual steakhouse has the hugest cult following of any restaurant chain

Texas Roadhouse has the most loyal fans in the industry.

The Western-themed casual steakhouse was the most likely to be recommended by its customers, according to a recent report by Morgan Stanley.

Texas Roadhouse was the most popular overall and with Baby Boomers and Gen X. It had average popularity with millennials.

Comparable sales rose 7% in the fourth quarter, while traffic was up by 5%.

Despite its popularity, Texas Roadhouse keeps a lower profile than competitors like Outback Steakhouse, Red Lobster, and Olive Garden.

The chain has about 400 locations around the United States.

It's known for giving away buckets of free peanuts at the table and encouraging patrons to throw the shells on the floor.
