Bally's in pretty typical for a strip casino. They don't really have any big attractions, but they do have quite a few restaurants and shops. Unless your going here for a specific place to eat, there really isn't any reason to go here over anywhere else, except maybe their exceptional Sports Book.
Bally's has a large casino area with all of the usual table games and machines. Their odds aren't very good, but you can't really expect good odds on the strip. Local casinos usually are far better for gamblers.
They have three areas of shops and restaurants. One outside bordering Las Vegas Boulevard, one that connects to the back of their property and leads to the Sports Books, and another that connects them to the Paris. It's more than your usual casino provides for shops and places to eat.
They have a very large Sports Book that isn't connected to the main casino. It's really cool and has stadium style seating and would be a great place to watch a game. Of all the strip casinos, this is one of the best setups.
Bally's is a perfectly normal strip casino. There are better ones and worse ones, and if your a tourist this place should be fine, but for locals there isn't much to do here over a locals place.
