When thinking of model places for workplace perks, the successful startups of Silicon Valley undoubtedly come to mind. And while heavy-hitters such as Google and Facebook are famous for their jaw-dropping employee amenities, up-and-coming mid-level companies are also getting in on the act.

Mashable took a tour of Zynga, a wildly popular distributor of some of the most played social and mobile games. When it comes to perks, the father of FarmVille doesn’t skimp. In fact, Zynga’s office is so loaded with perks and amenities, it would make working from home a bore.

Good Food

It’s not uncommon for tech companies in Silicon Valley and San Francisco to offer its employees catered lunches, but Zynga takes it further with meals cooked on-site by professional chefs. Each floor has a fully-stocked and themed kitchen, including a candy kitchen and a healthy “zen” kitchen.

Everything is prepared on-site — there’s even a pizza oven — and made with locally sourced ingredients. The company’s executive chef is Matthew DuTrumble, who was the youngest chef instructor at the California Culinary Academy and also had a show on the Food Network, Private Chefs of Beverly Hills. Want to eat some meat for lunch? The on-site butcher will take care of that in his two-floor kitchen.

If you’re more interested in keeping a good diet, there are always healthy options, including a fully loaded salad bar and freshly brewed Kombucha. The healthy options are an important perk, considering desk jobs are notorious for helping people pack on pounds.

Good Fun

In the basement, there is a lounge area packed with big screen TVs, a curved wood bar area and free beer on tap. If you’d rather unwind with a workout than an ice-cold beer, you can hit up the Zynga gym. Employees can take CrossFit classes, meet with a nutritionist or schedule a free massage.

And if you want to work and play with your canine friend, he’s more than welcome — every day is bring your dog to work day at Zynga. After all, the company is named after the CEO Mark Pincus’ late dog, Zinga.

Work Hard, Play Hard

Zynga provides hotel-like amenities to keep employees happy and retain (and attract) talent. Tech companies in particular are notorious for providing awesome on-site perks to encourage employees stay at work longer and up their productivity. Facebook offers employees a free shuttle to work, plus numerous “micro-kitchens” stocked with snacks, and a free cafeteria where employees are welcome to invite family members for lunch. Google has a golf course, basketball courts and nap pods for a mid-day snooze.

Zynga churned out six games in the first quarter of 2012, so the team is definitely working hard. Despite the long hours, the employees’ access to a spacious top-of-the-line gym, a team of chefs and all the free beer you can drink makes for quite the hook-up.

All the perks in the startup world make sense — several Gallup studies have shown a correlation between productivity and worker happiness, and Gallup estimates that organizations whose employees are not happy and engaged lose out on billions of dollars in potential revenue.
