In BrE, we go to church (to pray); college, school or university (to study), to work [n] (to work [vb]); to hospital (for treatment).
However, we go to the cinema (to see a film); to the theatre (to see a play), to the ballet and the opera; to the pub (to drink).
We listen to the radio, but we watch television.
We go to work, but we go to the office.
We go to hospital, but we go to the doctor('s), the chemist('s).
Articles are indeed a tricky subject.
