Hi Rajan, shame I will not be around, as I will start vacation tomorrow, and will head south. Thanks to the long summer days, yesterday I went out after work for a stroll in Lisboa, to test my new Fujifilm XE-1 and 18-55 lens.
Nothing special really, just out and about on familiar places. If you have the time, you absolutely have to go to these successive belvederes around the Sao Jorge castle and Se areas: Portas do Sol (wonderful view of the old town and river), Graça, and Senhora do Monte. The last one provides the best view of the city. You just have to walk uphill and follow the tram tracks
Quite recently, a new belvedere opened, atop the Arco da Rua Augusta, overlooking Praça do Comércio near the river. This Praça is the "welcoming hall" of Lisboa, and a must see.
Finally, if you have the time, and are not on a diet, head out to the Belem district, to savour the famous "pasteis de Belem", a sort of famous cream/custard tart. The recipe is secret, comes from when the monks living on the nearby Jeronimos monastery were expelled from it during the liberal revolution in the 1820´s... the recipe is known only to 4 pastry chefs, not even the owner of the shop knows it...
