Coliseum Cafe has officially opened its PJ branch last July 7th :D
It is located at Plaza33, Section 14, which is the neighbouring building to Jaya33. It occupies a whole corner lot on the ground level- quite impossible to miss actually.
Having tried the Ox-tail Soup, Hailam Mee and Hainanese Chicken Chop, I am happy to report that the taste remains authentic, just as I remembered it from long ago.
There may be restaurants with much higher quality cuisine but for enjoying good food with a certain atmosphere, I hope you'd give it a try ;)
