Desserts by Michael Allen, at 1015 Fulton Street between Grand and Downing, is still in “pre-opening.” Later this week, wi-fi and chairs are coming, so you can sit and blog and enjoy a mixed berry macaron or creme croustada. If you fall in love with the treats, you can try to make them yourself. Their Web site includes recipes. Click through for an interior shot from our pop-in yesterday.
