Hi
You can find some info about Lisbon, Portugal here:
http://www.cm-lisboa.pt/turismo/
I think the site will be the same as in Mega02 the place is called "Cidade Universitaria" or "Estadio Universitario".
But I´ll give some insights.
Near the site (by car, or subway), there is a very good and big mall "Colombo" it has everything, also by subway you can get to the other interessant parts off the city where you can get good restaurants.
"Belem" area as also a´lot off good restaurants, you got to get there by Bus or Taxi.
Good and nice place to go eat but a litle more expensive (for you Brits is the same thing, you earn more than we do in Portugal) : "Docas de Santo Amaro" - by car. It´s a place near the river "Tejo" ( =Tagus river) with several restaurants.
Beaches - the nearest and good beach is on the other side off river Tagus, and it´s "Costa da Caparica".
Places for you to go after dinner.
"Avenida 24 de Julho" - a´lot off discos
So you better get a car.
But I think you will be very pleased with the wine bars / restaurants in "Doca de Santo Amaro". I usually see a´lot off Brits in there in Irish Pub, etc...
Hope this helped.
Cheers
