I am NOT a fan of Karsh's. When i moved to Phoenix many years ago, everyone made a fuss about getting their baked goods from Karsh's. I was really looking forward to what i expected would be wonderful baked things. They weren't. They were tasteless... Everything is the same tasteless flavor. There is pink iced tasteless, white iced tasteless... they have mastered the use of food color.... but it doesn't overcome the tastelessness. The only thing Karsh's has going for them is that they are a Kosher Bakery. I suppose that gives them a "captive" audience. There will always be a community of people who cannot buy their things anywhere else because they require Kosher goods.
There is one exception at Karsh's. They make a wicked fine Challah. Everything else leaves me flat.
