Received a text from this number saying my order was ready from Legendary Foods and I should pick it up at the walk up window. I have ordered nothing.

Just received a message similar to what Liz got.

The number belongs to Texas Roadhouse. I suspect someone has spoofed the number to interfere with the business by jamming their line with complaints.

I would sooner guess that someone simply entered the wrong phone number, unless you think that no one is capable of making that type of mistake.

It is part of their trademark: "Legendary Food, Legendary Service® starts with our legendary Roadies!"
As BigA mentioned, you and Liz probably were called by mistake from Texas Roadhouse.

Never ordered anything

So they texted you by mistake and after reading the other posts, you thought others would want to know that?

Apparently, the concepts of a "wrong number" and an "honest mistake" are unknown to many people in this day and age.  They seem to think that technology is infallible, thus they assume that what was actually a simple innocent error was instead aimed at them with malicious intent.  (As seen in the post by "OhioFlyer".)

I’ve ordered nothing as well and this isn’t the first time either that this has happened.

I just received a text from 855-540-1372 at 3:13pm saying my order is ready and to text HERE when I arrive. I haven't ordered anything and Texas Roadhouse near me is closed until 4pm
