I've been a regular here for about three years and have noticed a real decline in quality in the last year.
I always order the same bowl of rare beef, but they have become extremely inconsistent. Sometimes you get culantro, sometimes you don't. Sometimes the sprouts and basil are meagre and wilted and horrible, sometimes it is fresh and plentiful.
Recently it is definitely trending to being consistently bad. I often call for takeout and nobody picks up the phone. The broth is getting more and more murky and very dark.
It's really too bad, it used to be a great pho spot. Still very little good asian food in the junction and it filled that hole respectably.
