Thoughts: ok lar.
The dishes were generally heavy on taste. Dinner was satisfying. Price was reasonable.
It offers comfortable dining experience (despite without the air-conditioned) due to the high-ceiling structure with lots of hanging fans above the tables. The factory lot is quite huge with likely more than 30 tables.
This restaurant called "F4 陈秀莲鱼头" likely originates from KL's Chan Sow Lin which is a chinese village oppoiste the now closed military air port at Jalan Sungai Besi.
I think there have a big kitchen and a good number of waiters serving; average time of serving food despite a large crowd is maybe 15-20 minutes.
