Here in VA bars can still have a smoking area it just has to have its own ventilation system and there are rules regarding entry ways and the like.
Not every establishment can affors this but it is an option.
One of my favorite places with this is in Fredericksburg. There is an entry way with two doors inside of it. One for smoking. One for not smoking. The not smoking side has a decent sized bar and 5-10 tables. The smoking section has a 30ish foot bar, a lot of tables, a dance floor, and billiards tables.
Both sides, however, serve the same amazing chili.
