The venue can be found in build mode, for example, Gt to a blank lot and change it to whatever lot type you want, click build an buy mode then your going to see the pic in the right hand corner of the basement an right next to it your going to see a pic of a building called community objects, click that one an then you will find the venue its called Little Corsican bistro and I guess you can go from there, but you can only set up outside if you place it on a big enough lot

I  know im late but you should try going to edit town an then community lots an see if you find it.
