Next week marks the grand opening of a Corned Beef King restaurant that isn’t on wheels: The popular food truck has completed its buildout inside the Liberty gas station at Rockville Pike and Twinbrook Parkway. Owner Jon Rossler had been running a similar gas station restaurant in Olney for several years, but he closed it a few weeks ago when the rent got too high. He says he’s happy to have a brick-and-mortar location in Rockville, where many fans follow his food truck around and some have even been known to drive to Olney for a sandwich. Meanwhile, the former Corned Beef King truck that’s recently been seen outside Hank Dietle’s is now owned by a separate operator serving Latin food.
