Aomori Prefecture in Northern Japan produces some very nice sake, and Ringo no Hana is a good place to try it out. Some twenty different types of local craft sake are served either in ichi-go flasks or small 60cc tasting sizes if you want to explore a bigger variety. Adventurous drinkers may also be interested in their fruit- and herb-flavored liqueurs.
The home-style food menu - focusing on regional dishes such as grilled chicken and seasonal vegetables - is serviceable, but takes a back seat to the drinks selection. Budget around Y4000 at dinnertime, Y1000 for lunch.
