It really depends on what type of bar you go to. I went to a local bar and a a Corona was $4. Go downtown and its $4-6. But I prefer something on tap.. something off the IPA list. Easily spend $4 and up.
Nothing really has changed. Its just more is available. Location dictates pricing. I know here in VA, if you sell alcohol at a restaurant/bar ... your total Food sells have to be $2k per month. Most people don't eat food at a bar. So this is why some bars will charge more for beer.
