For me Seville is a more interesting place than can be realised from the top of the Giralda. Locals who are most likely to talk about this are the 'Camareros' (staff) in the local bars. I found out from one of them that many younger people congregate in a neighbourhood called La Alameda de Hercules. There are numerous eateries and bars there, but leave your valuables behind.
