After many months of delays and setbacks, the Corned Beef King food truck finally found its way home this week to the Montgomery Square Copenhaver Swim Club on Falls Road near Montrose. Truck owner Jon Rossler, whose family once owned the Celebrity Delly at Cabin John Shopping Center, signed a deal last December to operate from the swim club’s parking lot. After he was driven out by neighbors’ complaints, Rossler applied to the county for express permission to operate from that spot. This week he was finally back in business with everything from Reubens to mac-and-cheese plates to matzoh ball soup. (We tried the corned beef and were duly impressed.) Rossler is still working out the schedule for when he’ll be onsite, but it’s likely to be dinner-only Wednesday through Friday with longer hours on weekends.
