If you talk to a certain man in the tavern at a certain time, he will tell you of a password to tell the bartender
If you tell the bartender this password at certain times, he will lead you to a secret back door in the tavern to a special room full of illegal brews.
They have all kinds of dangerous drinks, foods, and combos that have been made illegal because of their dangerous nature.
The first drink on the list you see can be bought for $10.00 a glass. It's called Gore Brew. This drink has an alcoholic concentration of over 14% (hard liquor usually has 8% alcoholic concentration). It has a straight, filling flavor that feels like your mouth is expanding with the fumes. It leaves the aftertaste of a backstab, and gives a hard hit once it hits the stomach. The idea comes from the card Gore Horn, and it mostly comes from just the name. I will add to this post as time goes by. Feel free to add drinks and food to the illegal bar!
