“Great food and new location!“

“Longo Seafood serves up some tasty dim sum with solid flavors and good value. The Pork Offal Congee was a standout—rich, flavorful, and very affordable, which my parents really enjoyed. The Pork and Century Egg Congee was also good, though the portion was noticeably smaller. The Roast Pork was a highlight, with incredibly crispy skin that added the perfect crunch.

Overall, the food was delicious, though portion sizes varied. A great spot for dim sum, and we’ll definitely be back!“

“This is the first time I have dined at this restaurant. It was iHealth company dinner banquet in a separate reserved room. The food was fairly good overall, with jumbo walnut shrimp being my favorite dish! I also liked the sliced fish with vegetables and lobster with noodles dishes. I thought the Peking duck and sweet sour pork ribs were just average ...The atmosphere is festive, private party rooms are great, service is above average! I would have another company party here again!“
