. . . built in the new Los Angeles downtown by the architect and developer John Portman, whose other works include the various Hyatt Regencies, the Peachtree Center in Atlanta, and the Renaissance Center in Detroit. . . .they [these postmodern buildings]  no longer attempt, as did the masterworks and monuments of high modernism, to insert a different, a distinct, an elevated, a new Utopian language into the tawdry and commercial sign system of the surrounding city, but rather they seek to speak that very language, using its lexicon and syntax as that has been emblematically "learned from Las Vegas.""

There are three entrances to the Bonaventure, one from Figueroa and the other two by way of elevated gardens on the other side of the hotel, which is built into the remaining slope of the former Bunker Hill. None of these is anything like the old hotel marquee, or the monumental porte cochere with which the sumptuous buildings of yesteryear were wont to stage your passage from city street to the interior. The entryways of the Bonaventure are, as it were, lateral and rather backdoor affairs: the gardens in the back admit you to the sixth floor of the towers, and even there you must walk down one flight to find the elevator by which you gain access to the lobby. 
 Meanwhile, what one is still tempted to think of as the front entry, on Figueroa, admits you, baggage and all, onto the second story shopping balcony, from which you must take an escalator down to the main registration desk. What I first want to suggest about these curiously unmarked ways in is that they seem to have been imposed by some new category of closure governing the inner space of the hotel itself (and this over and above the material constraints under which Portman had to work). I believe that, with a certain number of other characteristic postmodern buildings, such as the Beaubourg in Paris or the Eaton Centre in Toronto, the Bonaventure aspires to being a total space, a complete world, a kind of miniature city; to this new total space, meanwhile, corresponds a new collective practice, a new mode in which individuals move and congregate, something like the practice of a new and historically original kind of hypercrowd. In this sense, then, ideally the minicity of Portman’ Bonaventure ought not to have entrances at all, since the entryway is always the seam that links the building to the rest of the city that surrounds it: for it does not wish to be a part of the city but rather its equivalent and replacement or substitute. That is obviously not possible, whence the downplaying of the entrance to its bare minimum. But this disjunction from the surrounding city is different from that of the monuments of the International Style, in which the act of disjunction was violent, visible, and had a very real symbolic significance--as in Le Corbusier’s great pilotis, whose gesture radically separates the new Utopian space of the modern from the degraded and fallen city fabric which it thereby explicitly repudiates (although the gamble of the modern was that this new Utopian space, in the virulence of its novum, would fan out and eventually transform its surroundings by the very power of its new spatial language). The Bonaventure, however, is content to "let the fallen city fabric continue to be in its being" (to parody Heidegger); no further effects, no larger protopolitical Utopian transformation, is either expected or desired.
