They officially opened their doors yesterday, September 8. The small parking lot was quickly overwhelmed. Between the overcrowded lot and the poor access, I'm sure they're losing a fair amount of business already. They're probably also doing a fair business, which is good for them. And they've mailed out coupons ($5 off on a $20 order), which is good for Rosemead residents.
Just as a heads up, Fresh and Easy relies on self-checkout. That's not a problem for me, but if you don't like having to scan and bag your own groceries, the store's not for you.
