A banana neon sign seems like a no-brainer. I won't bore you with my gibbering, but this neon sign is about 50cm high and has a USB powered power supply. It is unique enough to attract attention and it gives off a lovely yellow hue.
It's also extremely cost-effective which is a major pro. If you're building a home bar you want your money to be spent on the stock and the decor. Not at first.
