Jackson's Tavern looks a block from Adams B&G on the map, but in reality they are across the same parking lot from each other. And while Adams is surprisingly nice on the inside, Jackson's Tavern is true dive through-and-through.
It's smokey, and seems a little rough and intimidating at first, but we ended up finding the people to be pretty friendly.
There's a pool table and a Silver Strike machine, as well as a vending machine that dispenses lottery tickets. B bought a few and won $5, then bought 5 more tickets and won $25.
The restrooms are too tiny for sinks, so a communal sink sits behind a partition outside the bathroom doors.
Amusingly, when we walked in, the bartender thought B asked for a couple of "straws" when he in fact asked for a couple of "draughts". So there was some momentary confusion when she handed us two drinking straws. :)
