I enjoy shopping at QFC because their bakery always has great stuff and there are beautiful flowers in the florist area. Also, it's conveniently located about a mile or so from my house, so when I run out of an ingredient or need just one or two things, I always go to QFC.
However, their produce prices are pretty high, as well as prices on other things. I suppose if the paper grocery sacks have handles on them, they have to be charging extra to make up for the cost.
I find the employees to be helpful and kind, although I usually do have to track someone down if I can't find something. The seafood counter is wonderful, however, and I can always get my questions answered about how much fish to buy for the amount of people I will be feeding, or how to cook something.
It's fun to shop there, but I wouldn't do my main shopping there because of the higher prices.
