I don't plan travel around food, and I'm not a foodie, but if it is along the way, why not stop. I read about Helen's Sausage House online while doing research for a trip to Delaware. The reviews said if you were traveling near Smyrna you have to make the stop. I agree. Although you can't tell by the pictures, there was a non-stop line inside this place that opens at 4:00 a.m. each day except Sunday. For less than $4 you get two sausage on a roll. That's it! It's worth it the stop and I recommend going if you are in the area. Make no mistake, this is road food, but very good road food!
Helen's is the kind of place where even the locals eat. Frankly, there were a lot of locals and I saw plates from a lot of other states. This is not a place built or established for tourists, but one of those places that gained popularity by being good.
