Check out their menu. Their only steak advertised as USDA "choice" grade is their sirloin. They say it's their most popular. That makes sense since the rest of their steaks are obviously of a grade less than "choice". So the rest of their steaks are graded "select" at best, and possibly even a lower grade. Doubt they'll qualify as excellent.
