The Grind on Hayden is a disappointing facsimile of the Grind in Arcadia. In Arcadia, my experiences with the Sweet and Spicy burger, peppercorn burger, and mesquite wings were extraordinary. In the Hayden Grind this afternoon, mediocrity reigned as the barbeque burger lacked any essence of barbeque sauce, which was overwhelmed by the bland mozzarella cheese. The mesquite wings which Arcadia served plain were cooked less skillfully @ Hayden and covered with some superfluous orange-colored sauce. The onion rings were pretty good. The beer selection in both places is very good. I thought I had scored big when I purchased a groupon for the grind. Apparently, not so much. I'll drive to camelback next time.
