Not a fan.
Ordered food from here a few times, usually order it "low" on the spicey scale, but it's delivered and it's so overpowering that we can barely finish the meal.
The last time I ordered the green curry and I had a horrible stomach ache all night and into the morning.
The best thing that Sun Penang brought us was an Egg Custard Bun, which I've never tried before and was pleasantly surprised at how delicious it was.
