Shopped at Mariano's for the first time yesterday, on Elston. Although it is 20 minutes from my house, I think I will shop there fairly frequently. It is much better than my local Dominick's, which is not a good one, and more pleasant than the huge Jewel I might go to instead, and of course, lots cheaper than Whole Foods, where I have been shopping a lot.
Mariano's on Elston had a bigger selection of most things than any of the places I normally shop -- in many cases, a better selection of things I rarely buy, but in a couple of cases, of things I would like to buy but don't always find elsewhere. Hard to say if this is just quirky items or a seriously larger selection, but I think the latter. One item I expected to be able to get but could not find (and the place is so big, it may have been there and I just didn't find it) - a jar of pizza sauce -- not an item I look for often (can't remember the last time I bought one). They had some of the items I might go to an ethnic store to get, and had not marked them up outrageously.
Mariano's fruits and veggies were on average probably a notch less fresh than Whole Foods, but way less expensive -- though a careful examination of organic vs. conventional might explain some of the difference, I probably bought less organic at Mariano's, although they had lots. Beer and wine seemed to be about the same price. I am not a person who manages to remember prices well, but overall, everything else seemed less costly.
I didn't check out the cheese dept. or bakery, and have only a quick impression of meats, which seemed decent -- will know more after I eat the meat I bought.
Shopping at Whole Foods forces me to go to two stores, because some things they don't have and some things I refuse to pay their price for (paper products, etc., for one). Also, the prices are outrageous.
A piano player seems incidental -- yes, the piano was being played, but that will neither draw me nor drive me away.
Quite possibly the novelty of a new place to shop is a big factor. It feels like I might discover something new, which is possibly a delusion, but a pleasant one. Does this mean that my life has become pathetically boring, if I need a new grocery store to add variety?

Have I succumbed to the force of advertising, so I think a new shopping experience will alter my life?

I guess this is the wrong board to examine these issues. Or maybe the food really is a bit better at Mariano's.
