For a lesson in restaurant longevity, consider Greektown in Sunnyslope. After five decades, George Vassilou's welcoming and often boisterous eatery may not have changed much in décor, but the classic Greek dishes, hailing from recipes passed down by Vassilou's grandmother, are as fresh and flavorful as ever. There are the dolmades and spanakopita, of course, as well as loaded plates of lasagna-esque pastitsio, char-grilled lamb chops, and the shrimp Grigori, which includes prawns stuffed with rock crab. And if you want to spike your meal Greek-style with one of nearly two dozen kinds of ouzo — including a devilish moonshine version — Greektown is the place to do it.
