About

Onion Jack's offers a convenient dining option within the Harrington casino, often described as an upscale diner. While many guests enjoy the crab cakes and friendly service from specific staff members, others have expressed frustration with slow service and inconsistent quality, particularly with the prime rib. It is a popular spot for those using casino comps, but the 21+ age restriction is a point of contention for some families.
