If Batman does not like the way you run your joint, he will shut you down, Dark Knight-style. In Gotham, restaurants, bars, and clubs that run afoul of local ordinances don't get cute little letter grades posted in their front window like they do in L.A.. No, if your tavern gets a "B" grade that means he shuts you down - with a BIG ASS STICK.
In Batman #400, Batman drops in on The Belly of the Whale, a quaint establishment on the Gotham waterfront with a colorful clientele. It's the only place on the East End that has Bludhaven Stout on tap due to an arrangement the proprietor made with some local criminal types. The Belly's local charms are lost on Batman, who finds the following violations:
- establishment used as a front to push skag
- no hot water
- unclean food contact surfaces
- illegal sub-lease to supervillain (The Riddler)
- improper food temperatures
Wow. Five violations. That's when Batman puts away the baseball bat and picks up the oar.
After administering his fine/punishment, Batman advises the proprietor on the appropriate course of action to correct the five violations: "Just close." The merchant is free to disregard Batman's advice, but is cautioned that he will return within 24 hours for another inspection - with an even larger stick - perhaps a fence post wrapped in barbed wire.
And that my friends, is why it's safe to eat out in Gotham.
