Customer Testimonial

New Capital Seafood has the best dim sum! And for dinner, you must try their amazing spider crab.

The plaza is getting even better, with new additions like Boiling Point Hot Pot, Creamistry Liquid Nitrogen Ice Cream, Duke Bakery, Gen Korean BBQ and Junkabok.

It's a fun place to hang out with your friends for a casual night. They also have a clothing shop where I've found some cute accessories.
