Maxim Dim Sum makes pretty good Dim Sum, they are in Sungai Dua, Bangunan Lip Sin. If I'm not wrong they are a branch of Max Gourmet opposite Queensbay?

For Mee Goreng, I personally think that the one in Pulau Tikus market tastes better, it's in a kopitiam but I don't know the name, it's very near to the Jalan Bangkok one, just opposite it (one road away). I've heard the one near Fort Cornwallis/beside Esplanade tastes pretty damn good too but I never had the chance to try.

Gurney Drive Wan Tan Mee worths mentioning too, they're special as they're spicy (麻辣/ma lat)
