I know this is a longshot, but my wife and I visited Lagos in 1988. We met an Irish couple who ran a bar there and we went there quite a few times when we were on holidays. They were a really nice couple and I think they had a couple of small kids at the time.
Does anyone know if there's a couple matching that description that's still in Lagos? We're going to Alvor next weekend and would love to drop into their bar (if it's still there) for old times sake.
