One of a group of dispensaries operated under the Frosted Leaf umbrella, the Federal spot is conveniently located just south of Sixth Avenue, in the Barnum neighborhood. There's a decent array of flower on the shelves, but what sets this Frosted Leaf apart is the assortment of concentrates -- dozens of strain-specific shatter options at reasonable prices. And the edibles in the store will stretch the eyes of any sugar fiend who also happens to enjoy cannabis. Frosted Leaf also has a website where you can shop for and purchase flower, concentrates, edibles and accessories online, then pick up your items in the store -- and tax is included in all listed prices, so you'll know exactly what you owe. There's also a blog on which employees plug new items and discuss their favorite products, which might help those who have trouble deciding what to buy.
