I looked into Q-Doba catering (I LOVE, LOVE, LOVE Q-Doba!!) BUT it was SO expensive....I did this myself for about 1/5 the cost of Q-Doba catering!!
I did not take any pictures of the food table ~ as a person that takes bookoo-bunches of pictures, I don't know how that slipped by me!! I do have a couple pictures that I think you can get an idea of how I set it up!
I had the plates/silverware, followed by the taco shells and nacho chips, then 2 roasters for the meats, lettuce, tomatoes, onions and cheese, then sour cream, salsa & taco sauce....then I had the nacho cheese in a crock pot and some other munchies on the end!
I had the candy bar set up to the right ~ and had the guest book/card box on this table. You will notice a helmet next to the card box ~ my son is crew chief on my sister's race car ~ and he himself does some racing and LOVES it!! Instead of a guestbook that will get put away and probably never seen again, I opted to get a helmet for people to sign this way he can display it on a shelf or something and always have it to remember his graduation!!
I had the candy bar/card table to the right ~ then the food table in the middle ~ and coolers for drinks to the left!!
I also rented a tent with tables and chairs for shade seating, and the unfortunate possibility of inclement weather ~ thank goodness we were blessed with a perfect day!! We also had horseshoes and corn hole (otherwise known as bean bag toss!) to play. I also rented 2 port-a-potties to cut down some on the in & out of the house.
I know you said you were set on the cake ~ I just thought I would show you the one I did for my Zack!! I was going to use Kindergarten/Senior pictures, but decided to go with baby/Senior pictures instead!! Everybody commented on how cool the cake was!!
If you have ANY kind of questions ~ feel free to ask!!!
