TripAdvisor did an analysis of room service across the world:

• The average total cost of room service in American cities is $55.
• In the rest of the world it is $45.
• Denver, Seattle, and Minneapolis have the cheapest room service in the US.
• Las Vegas, New York City, and Washington D.C. are the most expensive American cities for in room dining.
• Three of the cheapest cities for room service around the world are in Africa. The cities are Tunis (Tunisia), Cape Town (South Africa), and Marrakech (Morocco).
• On the other end of the scale Scandinavian cities such as Helsinki (Finland), Oslo (Norway), and Stockholm (Sweden) will make you pay dearly for your food.
• Surprisingly the price of the hotel you stay at has no correlation with the price you pay for room service.
