This is a great place to buy wine...but for the people like me, who like wine and beer but really could do without, there's the cheese.
Glorious cheese!
For the beer: this is the place to stock up on weird ciders (maple flavored yum!) and all varieties of New Glarus.
The wine selection is particularly good for whites, which are a bit trickier in my experience. Also, the prices are right!
Don't be afraid to look like an idiot here, just ask for what you need. The service is exceptional.
