A dry bar (no plumbing or electrical changes) typically doesn't require a permit. A wet bar with new plumbing usually requires a plumbing permit ($50-$200). New electrical circuits require an electrical permit. If the bar is part of a larger basement finishing project, it falls under the overall building permit. Check with your local building department — requirements vary by jurisdiction. A permit typically involves inspection of plumbing and electrical work before walls are closed.
