I've been to Dublin for work and leisure a few times, always with colleagues or with family. I'll have a weekend alone in Dublin in May, so I'm hoping to find activities and/or restaurants that are good for a single traveler.

I've already seen a number of the city's major sites (Guinness Storehouse, Old Jameson Distillery, National Museum of Ireland, Phoenix Park, Writers' Museum, Christ Church Cathedral and Dublinia). Outside of Dublin, I've been to the West Coast, Aran Isles and Ring of Kerry. Since I'll be arriving on Saturday morning and need to be at work in Dublin on Monday morning, I don't want to venture too far afield.

Currently, I'm considering a visit to Malahide Castle and/or a day trip to the Boyne Valley, so thoughts on those - as well as other suggestions - would be much appreciated.

TIA!
