Ladna is a Thai style noodle, quite interesting and actually not bad.
There is a "Thai Boat Noodle" Restaurant in Aeon Shah Alam (06.12.2017), and here is another similar yet different choices of boat noodles located at the ground floor of Utropolis Marketplace Glenmarie.
奶白 Nai Bak vegetable dish recommended by the lady boss was also not bad, it's garnished with tiny fried anchovies.
