When you are bringing a big group, look for one that will give you value for your money. This does not mean being cheap but getting a good meal that you feel happy about paying. You are satisfied for what you get. As an example in Thailand, why would I pay $25 for a Pad Thai that tastes average in a restaurant when I can buy a better tasting one in the street for a dollar? Or, in Hanoi, the street restaurants offer local food that are more tasty than in fancy restaurants.
