Not a quick thinker on my feet, I was a little confused at first. But, the teenager behind me guided me through it. There are enough signs and recommendations along the way so you won't mess it up, but the best piece of advice is to go for low sweetness when adding the sweetener.
If this were next door or within biking distance of home, I'd be a regular here. But, alas, the parking in this mall, Pacific Rim Plaza, is positively hopeless so it'll be forever and a day before I can make it back.
