I'm not sure where you're from, but I don't know why someone would think food is lower quality here. Sure, the bread might not be so great, compared to fresh baked italian bread, but things like meat, poultry, seafood, pork is second to none in HK. It's fresh, and cheap, and you have a LOT to choose from. Eventually you'll find the best places to go for each (and will likely all be in the same area) and you'll be enjoying delicious fresh food for dinner every night.
If you eat at food courts all the time, and crappy chain restaurants like spaghetti house, then yes, the food will suck.
