If you're low on gems, you can earn more by playing other restaurants you've unlocked and collecting their every-five-stages rewards, testing your luck on the slot machine, or replaying stages and completing achievements to earn EXP and level up.

While 'spend gems on upgrades' is an obvious way to improve your scores and progress through the levels, it's even more necessary in this location simply because of its high difficulty and cost. However, if you want to actually complete all forty levels, you're going to have to shell out even more gems on upgrades: only one area of the Hell's Kitchen interior can be upgraded with coins alone, and nearly every kitchen upgrade will cost gems even at level one. Merely unlocking Hell's Kitchen has a significant upfront cost of 10,000 coins and 15 gems.

Our tips below will help you maximize what little you have to work with so you don't get trapped in kitchen purgatory. Hell's Kitchen is the most challenging restaurant yet, with minimal amounts of cooking utensils and surfaces available to start and high costs for upgrades.

The latest update added a new location for digital chefs to master: Hell's Kitchen, which attracts diners with its pan-seared tuna, peach iced tea, and modern décor. Players will cook and serve a variety of dishes to walk-in customers, including cakes at a bakery, hamburgers at a fast food court, lobster at a seafood bistro, and plenty more. Cooking Fever is a time management simulation that takes place across a series of themed restaurants.
