It's a STEAK HOUSE MEANING DINNER
It's' the same reason why some restaurants are closed on Mondays but open on Sundays. It's just the times that they can maximize their profit potential and do the best business. It says as much on their homepage. Also remember that this was a corporate decision, and local exceptions are considered very carefully. It is open for lunch on the weekends, but only serving dinner helps the restaurant to operate without typical slow downs between mealtimes and gives their managers more free time during the day.
Yea they don't open till 3:00
