Warning: Only go to Total Wine if you have a lot of time to kill.
The vast selection of qualify products can easily distract you for hours.
They do tastings AND classes.
The prices are as good as or better than most grocery stores in town.
Also, they provide beer and wine literature at the front of the store.
I am aware of the competition and like them just as well, but when it's time to stock up on booze, I choose carefully.
