I'm at King's College, UoL. It has a great Law Dept in terms of teaching staff, and the majority of toay's eminent professors and Dons at Oxbridge have been at KCL before going there. The problem with KCL law school is that it is very disorganised and its facilities are shabby apart from the great Maughan Library.
I got 3 AAA's at A-Level and am currently doing the LLB/Maitrise en droit course at King's. The only problem with King's is that its reputation overall doesn't match up with that of UCL or LSE, though the Law school at King's is without a doubt better. However, word of warning: take the league tables with a pinch of salt - some schools may have worse teaching grades, but make up with a better pupil spend score. King's don't spend much at all on students but their teaching is some of the best in the country. In fact fellow law schools tend to give King's a very high rating.
