I like the Sonoma Chicken Salad at Whole Foods better.
I need to try that. The Waldorf Chicken Salad at Fresh Market is very good too. The Coffee Bean on Coursey makes the best CS sandwiches in BR IMO.
The best CS sandwich that I've ever had was at Elmwood Fitness in Harahan several years back.
Those are all chunky chicken salads, whereas Calvin's is not. Still though, there's just something special about Calvin's CS. I crave that stuff.
