    This is the neighborhood fish joint we’ve been looking for. Small, friendly and perfectly cooked seafood dishes that are well priced. Nothing pretentious, just great seafood in a family run kitchen. The softshell crab is what we came for which was in season and lightly fried, the fish and chips and the panko fried sea bass were all delicious. We are so happy to find this little gem and will be back often.

    I cannot imagine anyone NOT loving this place. We traveled 1.5 hours into Phila. As we often do. Everything important was great..food…service..pricing etc. four of us all had different entrees plus desserts. Everyone loved it! The server “Milan” took care of us with great service and answered questions accurately with recommendations…the owner is clearly hands on..portions were nice on 3 of the meals, but the fried combo platter was huge. We commented on, and were amazed that any food that was fried, not ZERO grease and wetness to it. Fries, founder, shrimp and scallops were all breaded with no evidence of frying AT ALL…are you close to others? Yep..pain in the butt to park? Yep But…we thought it equal in food quality to very high end places that we frequent in Phila.

    The waiter was super, little quaint place, enjoyed that you could have a conversation without the music blaring over your conversation, gave plenty of food and it was all very good.

    We ordered the soft shell crabs here because we've learned that Seafood Unlimited knows how to prepare them. These delicately-flavored crabs come sautéed with very light breading; consequently, one tastes the delicious car, not a heavy coating of fried dough. Served atop spinach risotto, also delicate in flavor for a perfect complement, the dinner was expertly prepared, served efficiently, and was thoroughly enjoyable. This small, neighborhood gem does seafood right, is fairly priced, and is a local business run for years in a quality way. We recommend it without qualifications.

    Nothing really to brag home about. The food was ok, sort of generic standard menu at a fish eatery. Nothing on the menu stands out or tastes like it would make you want to go back. The service was nice, ambiance was good.
