When will the lunch orders for Ruth’s begin (steak break)? For those who haven’t tried it - it is a really good take out lunch you can pre-order and grab without waiting in long lines. 

Nothing on their Facebook page, and I would be very surprised if they did this without announcing it there.

(FWIW, I tried this once and was decidedly unimpressed, but that's neither here nor there.)

I don't think that's the main reason here. Head Soccer

Lunch orders for Ruth's Chris Steak House's "Steak Break" typically allow pre-ordering for a quick and convenient takeaway without the need to wait in long lines. slope
 

I haven't tried it yet but I Merge Fruit will test it out to see how it goes.
