No probs. i'm from that city originally and I know what I'm talking about. Southside is best, just yesterday a stabbing happened at a club on the northside, the guy died. Shit like that don't happen south of the river.
No offense Northside Dublin people, but you know it's fucking dangerous there for decades!
some of the hotels in Temple Bar area have grwat clubs downstairs, and you can chill on a warm night outside takeing coffee on the plaza. Street entertainment also. take a trip in daytime to Bray, nice scenery too

And P.S welcome to my homeland, or as we say in my language. Fáilte go nEireann, is go n-éirí an t-adh leatsa!
Slán go foill.
