This is one of more spacious Bio&Bio stores. However, perhaps because of it being so far from the city centre, it doesn't seem that well stocked. On some occasions I shopped there, something I needed had been sold out (nutritional yeast, umeboshi vinegar, light miso, vegan ice cream).
I like to shop there when I visit the Arena centre, because the store isn't cramped, the staff is friendly, and now it's possible to check on the Bio&Bio website which product is available at which store.
Cons: location, some products out of stock
