You will wait (if you don't call ahead), but it will be worth it. With that being said.. call your order in before you go. They usually have a separate line where you can pickup call ahead orders too. If they don't pick up the first time you try calling, call again.
While there are plenty of options, I tend to go the traditional bacon, egg and cheese route. With pimento cheese, of course.
Check in on Yelp for a free fountain beverage! They do also have a frequent buyer card that you after you buy 10, you get one free.
Seating is fairly limited, and with how many people are usually waiting, I prefer to just order to go. However, there are about 10-15 tables if you can snag one and don't mind people standing around you while you eat. You will be too enthralled by your sandwich to really even notice.
Was a little confusing the first time figuring out how to get inside. They are located in a multi-tenant building, so you will need to walk into the establishment's main doors, and will then see the entrance to Owen's on your right.
