I feel bad for anyone who thinks that this place serves good pho.
The 'rare' beef was basically cooked, circular slices of almost-lunch-meat-grade beef and the stock was almost flavourless aside from the MSG. The beef balls were so puny... I've never actually seen balls that small (ha) so I guess this place was worth it just for the novelty of experiencing tiny, shrunken beef balls.
Please do yourself a favour and skip this place. There's lots of other good pho joints to enjoy in and around this area.
