In addition to free pretzels and hot dogs, Full Circle Bar offers use of their skeeball machines for free on certain nights (before you get any ideas about a Christmas gift, just know that skeeball machines cost about $4,000-$5,000 a pop). It's like killing two birds with one stone, because playing skeeball is technically exercising, right?
