I've been three times and I've loved everything I've had. I don't detect a weird shortening taste.
Actually, I disliked Iggy's bread. I don't like sourdough! I'd much rather have the danish pastries.
The napoleon's hats are especially good. And the 9 grain bread - thinly sliced, toasted, with smoked salmon and butter.... But you better like marizapan for the sweet things.
