I don't generally patronize Starbucks. For one thing, I'm not a coffee drinker. However, wife and daughter are. They both love the coffee here (in general). So we popped in this morning on the way to dropping daughter at a friend's house, and on our way to work.
They got, and seemed happy with, their pricey coffees. They also bought me a pricey "old fashioned" donut. The donut was really good. I don't think it was $1.50 good, but it was vastly better than Dunkin or any grocery store donut (which isn't a very high hurdle to clear, I admit). If they weren't so pricey I'd give them four stars for quality of food and beverages.
In summary: very pricey, but pretty good. If you want to splurge (or are rich enough you don't care about price), come to Starbucks. This shop had friendly staff who moved quickly.
