Inconsistent broth at High Street Cart Noodle

Since my last visit, I was craving for that strong broth again, but unfortunately it was bland this time and you can see how light it is compared to my first visit.

Although the broth wasn't that good I was happy because I saw Joey Yung 容祖兒 and Wilfred Lau 劉浩龍 leaving the joint right in front of me so I guess the rumour is true that they are an item.
Sammi Cheung was also there but a few weeks ago.
