I'm not young either but the Pumphouse hotel in Nicholson St (opposite the Exhibition building) and the Redback brewery in North Melbourne aren't bad pubs. Bridie O'Reillys (a irish pub) in Little Collins Street near Parliament house isn't too bad either. The elephant and wheelbarrow in Fitzroy St, St Kilda does the English pub thing. If you want live music as well then stick to the inner city - Fitzroy, Richmond or St Kilda. Food wise you'll find Brunswick St cheaper than Lygon up Carlton/Fitzroy way.
