Be careful when traveling, especially during the early part of the game. Travel expenses cost money and steadily increase awhile. There are some locations you must travel to in order to purchase ingredients, test recipes, etc., but do not have a shop available to buy your inventory. When going to such a location, make sure you have enough money to make the trip back. You will not be able to earn anything while at those location. If you get stuck there, the game is over. The following is a list of locations with no shops.

Falkland Islands
Gobi Desert
Las Vegas
Reykjavik
Uluru
Xunantunich
