Only weeks after Pittsburgh got its first tart frozen yogurt stop, we already have a second, this one in Oakland. Sweet Berry is a chain with a number of other locations in California and the Washington, D.C. area, but this is the first one in Pennsylvania. They have two types of frozen yogurt, plain and honeydew. A small is $2.99, $.50 extra for honeydew; toppings are $.99 for one or $1.49 for up to three. They include sliced nuts, fresh fruit, cereal and (my personal favorite) bits of mochi. The yogurt at Sweet Berry isn't as tart as some natural frozen yogurts, though it's still low in sugar. They also have smoothies and Seattle's Best Coffee. The web site is still under construction. Check it out at 115 Meyran Avenue (between Fifth and Forbes) or call 412-235-7623 for more information.
