Description: Despite the name, shot bars usually aren't actually for throwing back shots with the bros. Instead "shot" here means the main focus is serving whiskey neat - so don't expect to find a wide variety of options for complicated cocktails. If you're interested in whiskey and only whiskey, these can be great because prices for the same whiskeys tend to be lower than ordinary cocktail bars.
System: You might pay otōshi and get some nuts, but otherwise, you'll just pay for the drinks at the end of your night.
Budget: They should have lots of great pours available in the 800-1200 yen price range.
Making friends: Allowed.
