This game is easy
day 1: get one more server
day 2: get 50$ upgrade
day 3: get one more server and 100$ upgrade
day 4: get one more server
day 5: keep your servers at 3, and do not upgrade anything that gives you extra seats (it slows your serving speed)
Keep the price of eating at your restaurant high enough to spend all your customer's money.
After you reach the point where you have all the upgrades up until the $1000 (minus any +seat upgrades), then save up $2000 for the delivery upgrade
Next, save up $3000 for a new restaurant, and repeat the above process for your first restaurant until you have all the restaurants. After that, continue upgrading your restaurants and feel free to add seats (but add more servers) after you use up all the +price only upgrades
Not very hard... you just kinda need a lucky first day, then get parachute and extra rocket fuel and glide down slowly on days 2/3/4 collecting all the coins and not hitting the ramps
