Yeah, no. This is a non-starter. Restaurants have high price elasticity of demand - higher menu prices cause a significant fall in demand because there are alternatives to dining out (you can choose to eat at home for food, you can choose to see a movie for date night; even if you still decide to eat at the same restaurant after they jack up their prices, you can still make choices to lower your bill, such as not ordering drinks or appetizers).

Compare this to food you buy in the grocery store - you still need to buy food, even if food prices double overnight. You may buy less of it and pick cheaper brands, but your fundamental consumption habits will not change much.
