The Forest Inn, 5849 Washington Blvd, Arlington, VA 22205 , has a Genie in the back set to 50 cents for 3 balls. The 3 special scores are set to award extra balls and are set quite low for the first 2 extra balls and a little more chalanging for the 3rd extra ball so it's really more like 50 cents for at least 5 balls. Scoring is a bit more robust on the 3 ball setting as well. The location sells food, mixed drinks and beer - nothing too fancy. It's located just a few doors down from Westover Market, www.westovermarket.com , that has over 1,000 different types of Beer for sale and good grub to boot, so both are quite interesting places to check out.
