In the northern 'burbs, one addition and one possible subtraction.
In the Mitsuwa shopping center (Arlington Heights Rd. and Algonquin), a new place has opened up in the food court. It's back-to-back with the Hippo Bakery, where an ice-cream-and-crepe place had closed in 2005. The new place is called Re Leaf. As the name suggests, its specialty is tea, primarily matcha tea, which seems to be "in" right now; but they also serve about a dozen flavors of ice cream, including "exotic" ones such as black sesame, lychee, and plum, though I didn't try them. They also serve some desserts, both ice-cream based and not. The latter includes two varieties of dango (grilled sweet rice dumplings), which were interesting; but, like traditional Japanese sweets in general, I suspect to most Westerners they'll be an acquired taste.
The possible loss is the Dessert Gourmet in Glenview. I've driven by several times in the last few months during normal business hours, and each time they've been closed. On the other hand their sign is still up, the fixtures are still there, and the power is still on, so perhaps the owners are just taking an extended vacation.
