kim says This restaurant is amazing!! It is so unassuming on the outside; you barely notice it and likely wouldnt even drive down the street it is located on if you weren't a local. We went there this weekend after visiting this site and looking for places close to old orchard beach. When we entered the "dive" we were hit with this amazing character of the place. It really has a great vibe. I ordered huevos rancheros with a side of hash and my fiance ordered the fishermans breakfast. I have to admit that I got a little frustrated when we got to 1 hr past ordering and we still hadn't received our food yet. BUT let me tell you... it was completely and utterly 100% worth the wait. It was by far the best breakfast joint we had ever been. I order Hash every single place we go because it is my favorite breakfast side. There hasnt been any place in the US that I have been that even comes close to the flavor packed into this side dish. My fiance's meal had homemade sausages (PACKED with flavor) and homefries with sweet potato in them. The effort they put into the dishes is clearly seen and it is evident that the food is all made from scratch. We loved this place so much we returned later for a late lunch. IT did NOT dissapoint. I loved the lobsta sandwich, clam chowder, and crab cakes! The sandwich had a nice thin dressing that highlighted the taste of the lobster and did not take away from it. The crab cakes were light and airy and packed with flavor from the red peppers and onions in them. My fiance loved the fish sandwich. We will be coming back to the porthole diner for years to come for the food and atmosphere.
