re: I'm coming to Baton Rouge in a couple of weeks

I'll echo the upvotes for The Chimes, City Pork, Overpass Merchant and Beausoileil. All of those places have really good food that's priced right. Chimes and Overpass have good beer selections too. Sammy's is fine, it's just kind of far from where we live.
The Bulldog is a big beer bar. The food isn't great, but they have a big selection of beer and a bunch of TVs. Corporate Brew and Draft probably has the best beer selection in town, but they don't really offer food. Although they don't care if you bring in food and they're right by Albasha, which is the best Greek/Lebanese in town.
If you're going to buy beer, go to Calandro's Supermarket. The Perkins location is a bit better than the Government Street store. Bin-Q Liquor on Perkins also has a good selection.
