Cheapest place to eat ......
Champ's Volunteer Cafeteria - FREE!
Volunteer to work at Champs, and you can get free Breakfast, Lunch, and Dinner. For students, Field Reset, safety glasses, etc. are typical event jobs. The great thing about Field Reset is you get to watch the competition from the Field. And, if your Field Reset Team is the "best", then you will get to be Field Reset for Einstein.
For the Mechanical Mentors, Robot Inspector is a great gig.
