that's your best bet. i don't like their layout, but they have the best view around if you're up front, and each table can set which game to set its speakers to. I'd definitely go there before any other casino.
I'm pretty sure Hooters in Biloxi has DirecTV, which doesn't carry CSS. Don't know about the Gulfport Hooters, but it's talent has always been lacking.
The Island View has a couple decent small bar areas, and it's actually in Gulfport.
Shady's has a pretty good bar to watch a game at, when it's actually open. Great food too.
Half Shell Oyster House in Gulfport has a decent bar, but there's no reason to try to watch a game there. Ditto for the Lookout. Neither of the bars on either side of it are sports bars.
Otherwise there's plenty of Chili's, Applebee's, etc. to choose from.
Edit to add: BWW in D'iberville has DirecTV too.
