Gourab Banerji's office is fantastic. He is great, no doubt but his office has some fantastic people. Anyone interested in litigation or arb should definitely consider his office. But with senior counsel you are probably worrking only on research, while with drafting/younger counsel, you will look at evidence, reply, etc as well. Good learning opp for sure
SAM, KCO and Aarna. Others are either too small to have sufficient work for an intern, do mostly litigation related to arbitration and not "real" international arbitration, or just plain too unpleasant.
