Concierge.com's insider take:
Without a doubt, this refurbished 174-room hotel off the Grand'Place is the most glamorous in town. It's part of the small, silky Rocco Forte Hotels group and features the classical references, modern colors, luxe finishes, and witty details that characterize all 11 hotels. Here are leathers, linens, and velvets in mole gray, wine red, taupe, and chartreuse; angular dark-wood furniture; pure linen sheeting; and red- or green-marble bathrooms with art by the Belgian comics creator Hergé—i.e., prints of Tintin, Snowy, and Captain Haddock. The restaurant, Bocconi, is one of Brussels's rare modern Italians and a destination in itself (a typical dish would be Monkfish with asparagus and pesto).
