Need restaurant for business group

[BarbaraM48]

We are going to be in Buenos Aires for a meeting and need to do three nights of dinners. Upscale, if possible. International group including South Americans. I think we will do Cluny one night but I would like suggestions for the other two nights. The Four Seasons has suggested La Brigata ,Orvieto sand Savor. Does anyone have any suggestions? I was leaning toward Cabana Las Lillas because that is where people like to eat but it is certainly not my favorite.
