+1 to what Mirilis said -- I avoid The Winemaker's Shop, but it doesn't have a pizza place on the inside.
I think I know the one you're talking about though, but I've never been inside. It's west of campus near Grandview -- I think it's on 5th Ave? I just remember being surprised that it was a homebrew shop that sold food as well.
I think I was in the winemakers shop too. Is it near a country Restaurant called Tee Jays?
If so I agree lady was very rude I ended up walking out. When I went in she was sitting on the floor reading a book. I asked a few questions and it was as if I was interrupting her. I ended up walking out.
Definitely Gentiles. I was actually just in there the other day. They have a lot of the wine making supplies up front and an extensive selection of wines in the middle of the store. The back and walls of the store have the beer and beer making supplies. They are really friendly there for sure.
The pizza place is Mama Mimi's. They do pretty good "take 'n bake" business also.
I think there is another wine shop in Dublin, in the shopping plaza at Riverside and 161. There is a Tim Hortons in the plaza too. I think they specialize in building wine kits for beginners. I haven't purchased anything from them but heard they are pleasant to beginners and reasonably priced. The Wine Shop lady can be rude.
