Located in the Parque das Nações area (former Expo 98 ground) it is side by side with the Gare do Oriente station, the main entry point by train in the city. At a short walking distance from it you can find FIL (International Fair and Congress Room), concert room Atlantico Pavilion, the Oceanário, the Casino Lisboa and a few other points of interest in this modern and new area. The building itself was the main gate to the Expo 98 exhibition and has converted to the existing infrastructure right after it’s end. The shopping has a large supermarket, cinemas and an underground parking lot. Keep in mind it’s existence because :

• Eating – Since it has a area dedicated to restaurants and most of them being fast food / menu choices, it’s easy to get a cheap meal here, if you sightseeing in the Parque das Nações (Expo 98) area. On the top floor you also have some more expensive restaurants, if you prefer a quieter and better meal.
• Sights – The building is modern and connected physically with the Gare do Oriente station. On top of it, two towers where built in the last few years, the S.Gabriel and S. Rafael Towers. They were named after two ships that the sea captain Vasco da Gama used when he discovered a sea-route to India, in 1497.  I recommend the top balcony, that you can access by stairs close to the restaurant area. The balcony has a great view of the Expo area and of the Tagus river and has some shady spots with chairs were you can relax and have a drink.
• Shopping – Well, it’s a shopping, so yes, you can do that there.

The Casino Lisbon is worth seeing at night, when it’s working at full steam. It’s design is modern and it target a younger audience than the one that for instance Casino Estoril bets on. It has a lot of sitting space to take a drink, live music and circus performances. About the prices, their are about right, nothing too expensive. The casino also has a restaurant, but not the cheapest place around.

If you like gambling, welcome aboard. Casino Lisboa has more than 1000 slot machines, Black Jack and Roulette tables. Keep in mind restriction while traveling with children, since access is only allowed to people older than 18 years old.

Unless you are really into gambling, I would say that the casino is not worth the trip alone. But given what you can find the surrounding area, I would suggest an  afternoon walk through Parque das Nações (where you can visit the Oceanário, one of the world biggest aquariums), have dinner close by and have a drink at the Casino before returning “home” for a good night sleep.
