Most manufacturers will make something that will do this job - it seems to be a sector that has really got big recently. I think the bike that really kick started it was the Cannondale Bad Boy, and it does look fantastic (plus it has integrated lights and stuff), but you pay extra for the quirkiness (lefty fork for example). Your colleague might like that, or he might not. I don't think he could find a bad bike if he spends reasonable money from a known quantity, so it probably comes down to style more than anything else.
