Pho Phuong has been on our regular list for a couple of years and in the last 6 months or so the food has been very up and down; at its best, it's excellent - one of my favorite vietnamese restaurants. At its worst it's mediocre. I'd love to give it 5 stars for the days that it's on for me but it's too inconsistent.
I would describe the service as authentic - meaning it's up to you to get their attention at which point they are thorough, but don't expect them to actually wait on you.
favorite dishes are the beef salad with mint, the beef rolls wrapped in "exotic leaf", the ribs braised in coconut juice, and the broken rice.
Last word - beware the satay soup on the specials menu. The last time I ordered it, it was the hottest thing I've ever eaten - and I like hot food.
We still go back, but a little less eagerly than we used to...
