I usually have my Pho fix at home cause nothing will ever compare to mama's cooking. However, when I do eat pho out at restaurants I have to say my favorite place to goto is Pho Binh Minh which is located on 17th Ave SE the avenue of Pho restaurants basically.
Unlike I lot of places this place always uses FRESH pho noodles which makes a remarkable difference in taste. The broth is done just right and the thinly sliced beef always tastes delicious.
Not to forget about the other dishes available, definitely try out the Bun Cha Gio Thit Nuong (Vermecelli w/ Beef and Spring Rolls) and the rice dishes tastes great as well!
