The Tryp Lisboa Oriente was the first hotel built in the Park of Nations for the World's Fair of 1998 and it takes its style cues from that expo. A large mural depicting Expo '98 sits behind three dark wood reception desks. The lobby has a high cove ceiling with high hat lights. Large plants sit around clusters of low-back, contemporary chairs and sofas. There are three large saltwater aquariums on the facing wall of the mezzanine, visible from the first floor. The hotel's bar, in a palette of black, white, and turquoise features low tables with velvet stools and a banquette edged with plants that faces the street. Breakfast is served in a cheerful room within walls flecked with passport stamps, tailored cream-fabric chairs, and teardrop-shaped pendant lights. The overall effect is a clean, bright property with touches of style and efficiency that are ideal for business travelers.
