Q4 Chili's same-store sales of +6% marked our 21st consecutive quarter of same-store sales growth and again, significantly outpaced the industry. Fiscal 2026 saw this brand increase its lead as the number one casual dining traffic brand, and the results are sustaining year-after-year. We are very appreciative and proud that Chili's is one of the small handful of brands the American consumer trusts and we're willing to increase their visits to. By the end of Q4, we were selling 55 sandwiches per restaurant per day, an increase of 175%, and that number continues to build in the current quarter.
We continue to focus our efforts on both removing friction as well as improving restaurant throughput, as this is a key piece of our sustainable growth flywheel. The Ziosk software upgrade will reduce the manager time needed to resolve check issues, deliver faster table turns, and more importantly, improve the guest dining experience. The traffic growth reinvestment flywheel continues to spin and create sustainable, profitable growth. These updates are all contemplated in the FY 2027 Brinker guidance we have provided today.
As we close fiscal 2026, today's results highlight major milestones in Chili's growth journey. For the year, we reported total revenue growth of 7.9%, restaurant operating margin improvement of 30 basis points, and adjusted EPS growth of 20.6%. Turning to the fourth quarter, we continue to see strong year-over-year top-line growth, traffic well above industry averages, and restaurant margin expansion at Chili's. Our adjusted diluted EPS for the quarter was $3.07, up from $2.49 last year, a 23% increase.
