This is the darker Märzen beer sold in the US and elsewhere as Spaten Oktoberfest Ur-Märzen. This is NOT the golden Festbier sold at in Munich as Oktoberfestbier.
Huge selection! Regular prices are good for a specialty store. They have a very well priced clearance section. Staff is friendly. Some of the beers are quite old though (some had canning dates of 2017, so just check them).
