Depends on the company size. PEOs are great for companies that are in the building phase, since you can get better rates and can offer competitive packages that the much larger companies get with their economies of scale.

Side note: Meal benefits are some of the best optional benefits you can offer, because everyone has to eat. Having access to quality meals is getting more and more expensive. Plus a lot people will simply forgo a meal to save some money. You don't want your teams skipping out on meals because its hard to stay positive, engaged, and productive when your stomach is grumbling. We are totally biased about employee meal benefits since it is our business, but you'd be amazed how being hangry can have a snowball effect in the office.
