There are two ways a world-class, James Beard award-winning chef with a signature restaurant can go. Open another restaurant in a different city, train an executive chef to cook your food, and hope your reputation will suffice to attract customers. But then you take the chance of compromising the standing of not only the new restaurant, but your original eatery as well. Or you can do what Allen Susser, a.k.a. Chef Allen, has done. He's opened a gourmet market in the same shopping center as Chef Allen's, his namesake eatery, where he sells his homemade line of products such as marinades, salad dressings, and sauces. He also offers cooking lessons in the store the second Wednesday of every month ($45 per session), and provides an extensive take-out menu of New World items. It's a snap for Susser to keep his eye on both places, which hardly compete with each other, because Chef Allen's is closed for lunch. And it's doubly pleasurable for us to monitor the progress of one of our most loyal hometown pride and joys.
