Right next door to each other on Baxter. I always order spring rolls, frogs' legs and grilled pork chops. My scores are as follows:
Spring rolls:Nha Trang
Pork chops:Thai Son
Frogs' legs:Nha Trang
Decor and service:Thai Son
Close decision but I have to give the nod to Nha Trang. Any other contenders for Manhattan Vietnamese title? Pho should be a separate category.
