The 52nd-floor view from this classy lounge entrances legions of out-of-towners and even the most jaded Bostonians. A special-occasion standby, Top of the Hub offers live jazz as well as an excellent cocktail menu and wine list. Dress is casual but neat (no jeans). Open nightly until 1am. For a great view without the dress-up atmosphere, the Skywalk Observatory is two stories down.
