There's a pretty awesome little cooking sim here, once you get past the tutorial. You can upgrade your cooking equipment, pay for cleaning services at your restuarant, unlock new recipes, buy spices at the market, and it looks like they will be adding the option of hiring employees and mini games later.
There are tons of little touches that stand out like each restuarant having a different waiter/waitress helping you as well as getting unique regular customers with different tastes. I was even visited by a health inspector one day and had to show him that I could clean my dishes properly with a sponge. Best part is it looks like everything in game is available without IAP even though there is an option to purchase currency to speed up your unlocks. The world even has its own Yelp system called Yalp, where your customers rate your business lol.
At .99 Order Up! is awesome, the graphics are crisp, the controls are tight and precise, and the story/characters are pretty charming, but at free this is a complete steal.
