Run your own tavern, get people drunk and have the Monarch come and visit...and get the Monarch drunk...or just visit your toilet.
Fairly easy to get into and surpisingly difficult to stop playing. Four hours shot by before I realised. You can expand the size of the tavern, add new bars, cook, hire staff, hire researchers and a number of other things. You can reshape your tavern and its rooms at any point, though I'd recommed pausing at the start/end of the day and doing it then.
The early part of the game has some good, helpful pop ups, the rest of it hasn't, which is why this is only 4 stars.
Research can be a bit tedious once you get through the half way point as it takes an awful lot of doing to get the later ones while you build up an excessive amount of cash and nothing to spend it on.
Overall, for the price, it's worth it. It's entertaining, chilled, and fun.
