One of this year’s most heartening trends seems to be upscale restaurants taking a chance on underserved areas— no, it’s not as big a deal as grocers moving into food deserts, but it’s surely good news for any neighborhood to be considered stable and prosperous and interesting enough to attract an upscale spot. Now, what Acadia is to the South Loop and Bread & Wine is to Irving Park, a new restaurant called Razón hopes to be to Buena Park, a neighborhood we don’t think we’ve ever typed the name of here previously. (It’s basically the southernmost chunk of Uptown, between Wrigleyville and Montrose.) According to the Buena Park Neighbors newsletter, Razón, despite the Spanish name, is the brainchild of Serbian chef and managing partner Nash Cvetkovski, whose family has had the Beograd meat market and café at 2937 W. Irving Park for three decades. His aim is to create a modern restaurant using local ingredients and recycled/recyclable materials in decor and everyday usage. There will be a coffee shop with Lavazza coffee, inhouse pastries and sandwiches, gelato and even a flower stand; while the main bar and dining room will offer woodfired pizzas, Spanish-style small plate tapas like pulled pork and duck-fat fries, gourmet burgers and signature cocktails. The location in the Imperial Towers at 4250 N. Marine Drive gives Razón one other natural advantage— views of Lake Michigan. And lastly, good news for neighbors, there will be delivery. There’s no estimated opening date but Cvetkovski promises one soon.
