Congratulations on your engagement! We don't allow outside catering at any of our venues (Kellogg Center, MSU Union or Spartan Stadium). If you are looking for an outside venue on campus you could try the MSU Gardens. I am not sure on their policies or prices. Here is a link to their website. http://www.hrt.msu.edu/plan-a-wedding-or-event/
Wish you both the best!
