A strange one this, ADL are sort of old school 'Ivy League', not really regarded on a par with the Bains and BCGs of the world, and not part of the following herd either. In London, they used to have a lage office in Berkley Square above the Jack Barclay Bentley dealership, but I think that went during the downturn about 5 years ago when they all but closed their London operation. I have heard, though, that they're expanding again in London, but don't know much more than that. No doubt a fervent ADL employee will now put the record straight on this forum!
