Vintage Village Fine Wine at 28927 Southfield Road, Lathrup Village, Michigan.

This place has a good selection of German beer at great prices. Specifically they carry Weihenstephaner (Vitus, hefeweizen, seasonal) in the half liter bottles. Pricing is $3 a bottle or 2 for $5.50. I haven't found anywhere else that comes close to matching their prices. They also carry the half liters of franziskaner for the same price and 4 packs of ayinger 330mL for $13. They carry a variety of lambics too. The staff is very friendly.

*** of note the franziskaners I have bought the past two times have tasted a little off, perhaps a little old, there is no date on them. Everything else has been fantastic.
