BAR school or MBA or other master programs?

[mace]

I just got my degree in law in the UK. The obvious route next would be going for the bar school but i'm kinda sick of law right now and would like to try something different. My thoughts are to take up master in business or maybe the MBA. But I also know MBA needs 3-5 years of experience which right now I have no working experience at all as I am only 21 years old this year and a female, if that helps in answering my question. Should I stick to bar school next or go for business field? My family owns a listed company and perhaps it might helps to take MBA after gaining working experiences. So what do you guys think I should do now?
