I been reading some boards and some tricks include.
Sharing meals, appetizers and drinks. Go to a place that serves large portions of food like the double consommé of chicken and beef which can serve two people but counts as one appetizer.

At hotels you could get things like a box of donuts or cookies from entemanns, 2 liter soda pop, jar of salsa, large bag of doritos or potato chips, 6 count of bagels, and 64 oz orange juice. People could get chili fries, malts, half gallon of milk, salads, loaf of bread, peanut butter, bean dip, hot fudge sundaes, cheesecake and poptarts.
It sounded like you got a little snack but the smart people figured out how to get a lot of food off of the plan like you could get milk, juice, bagels and donuts for breakfast and save yourself one meal.
It is sad that people will reserve many times as they will not plan around reservations. How hard is it to make a schedule around meal times.
