St. Julians - Things to do

I'm headed to Malta in October and should arrive at my hotel in St. Julians (Intercontinental) around 3 PM. I am planning on spending the first evening exploring St. Julians and Sliema, having dinner in the area and wandering around. I'm looking for some recommendations for things to see, places to go, good restaurants and cafes. Photography is a hobby, so places where I can get some great images or views would be of interest. Thanks!
