The best thing in Valletta's Mcdonalds is having a huge window overlooking Republic Street. Here you can eat a hamburger inside while watching people come and go from the busy city. Otherwise, this is like all other McDonalds, perhaps brighter and noisier and always full of people (this is very, very central). There are tables and bar as you step in on the left. The WIFI works well, and does not require password even if you get to the bar its fine, though sometimes at the door you can get the network depends on the time). It is open from 8:00 to 23:00 every day, Friday and Saturday until 00:00.
