Yeah I have more bowls at Pho B where it was more heavy as you stated. I concluded that beef pho can be so inconsistent at times.
Also been times when it tasted more like a Saigon broth.
But man there has been a few times in which
(2 times) it was so pure!
Pho Huynh in El Monte seems to be the place in SGV for Hanoi Pho. Maybe @JThur01 or @secretasianman have tried it.
Since we are on the subject Round 3 Pho Noodle House in Rowland Heights caught my attention, you can get a beef and chicken pho with Hainan dipping sauces on the side. One Yelp review said the pho was less herbal and more beef based.
Quang Trung is solid and open late!
After Saigon style Pho I think the second most popular noodle is Hu Tieu.
