The results are the chain’s strongest transaction gains in four years and its best sales increase in three years, according to a research note from William Blair. Dive Insight:BJ’s strong second quarter reflected both its turnaround efforts and the brand’s positioning, CEO Lyle Tick said on BJ’s Q2 earnings call. “The seasonal Biscoff Pizookie was a standout performer during the quarter, with Pizookie incidents doubling year-over-year,” William Blair analyst Sharon Zackfia wrote. “Our saturation analysis suggests the opportunity for over 400 locations based on BJ’s current density in the L.A. market,” Zackfia wrote. BJ’s turnaround follows a similar trajectory to other successful casual dining brands — like Chili’s, which has outperformed the casual dining segment for several quarters.
