This revolving door location (8 Kneeland, formerly home to the original Pho Pasteur, Pho Mai, Pho 54, most recently Bangkok Crossing) is now open as Pho Thien Thien, and it's a respectable if not extraordinary pho joint with the usual assortment of bun, banh hoi, noodle and rice plates, plus a few family-style specialties. A decent beef broth, nicely rare ribeye slices, good fatty, chewy brisket.
Having brought someone who is new to Vietnamese cuisine, we simply got goi cuon, pho ga and pho tai nam, and cafe sua da. She will certainly come back. I'm likely to try some other things besides pho next time. One order of fresh rolls, two large-sized (the only size) bowls of pho, and two iced coffees came to $24 with tax and tip. Nothing to make me forget Xinh Xinh around the corner, but perfectly passable.
