My recomendation following a recent mid week trip to Dublin is to be aware that this place is a major den for drinking sessions of both men and women on party nights. This is not just at weekends, I was there Wednesday and Thursday nights about 3 weeks ago and it was awash with drunken people engaging in, puking in the streets, peeing in doorways, fighting, lying practically passed out in the street. The was a lot of police about but only seem to get involved when fights start. I went to Le Caprice and I found it from this webpage,

I am sure someone who knows the place better than me would know it.
