I've been coming to Ocean City for at least 25 years and I tried Anthony's for the first time last summer. Let me tell you, that this place has some of the best cheese steaks and roast beef subs that I've ever had.
Very retro feel to the place. They only accept cash, and the ATM inside charges $3, so always good to come prepared and bring cash.
I want to mention that my family has severe food allergies and they are very accommodating. Please double check with them if you try the place, but our allergies are: fish, shellfish, tree nuts, sesame, and beans. We are able to have fries and the majority of food there. Sub rolls are sesame free which is great. Please check with them as restaurants can always change ingredients or add new items that aren't food allergy safe.
The subs are a little expensive, but as other reviewers pointed out, they are packed and can be shared. I always recommend getting the small sub rolls over the kaiser rolls as I feel that you get more for the money.
Some other tips:
They have tons of condiments including lessor known au jus and horseradish.
My family will continue to visit Anthony's every time we are in the area!
