Your characters in any contemporary game will need to stop off for a drink, a chat, follow up a lead or whatever - and they'll need a bar to do so. Not to mention that barroom brawls are not the sole perogative of fantasy parties...
This is a fine well-detailed plan, at full battlemap size for those who enjoy miniatures, of a typical cocktail lounge/bar. There are plenty of tables and chairs, a bar with stools for the barflies, pool tables, a few arcade machines/one-armed bandits, even a juke box, and a large parking lot and garden for those who wish to take it outside.
Staff are provided for as well, there's a bar, kitchen, washing up area and office, along with ample storage. There's a staff restroom as well as public facilities.
The plans are extensive with several options including with or without a grid (hex or square), a daylight and night time version... oh, and the building's roof should a chase across it become necessary. There is also a black and white version if you wish to economise on printer ink. There is also a virtual table top version for those who are gaming online and cannot put the various panels of the regular version together easily.
It's nice, and extremely useful. If you run modern games, tuck this away - you'll need it one day!
