From behind St Patrick's you can enter the alternative neighbourhood of Fitzroy. Take Brunswick Street first and then go left on Gertrude Street. Then cross Carlton Gardens and walk north on Lygon Street. This will take to Carlton, the Italian district, where you can have dinner in any of its restaurants. If you are looking for goos pizza or pasta, try Tiamo, on 303 Lygon Street. If you are chocolate lovers, don't miss Kokoblack after dinner (167, Lygon Street).
You can also search for any event talking place in the city in the afternoon or night.
