Not really a bad place to go on half-price burger night, which is either Tuesday or Wednesday. They serve cheap pitchers of beer every night. I wouldn't tell you to stay away, because it's very cheap and the service was pretty friendly. But be aware this is a dive, although not quite as divey as it looks from the outside. They have a pool table and the when we were there a guy was smoking the whole time he was playing. So the Health Code is apparently not a big priority.
For a cheap bar/restaurant in the Falls, try River City Grill or Jimmy Biggs.
