Catering / Food options on a budget

Headed to Houston this coming week with my team to compete for a National Championship and we will be in town from Wednesday-Monday. Looking for suggestions on budget friendly meals / catering for 25, and a place to take them to dinner Sunday. We are staying over by Rice University / Houston Medical Center if that matters.

Our college only gives us $18/ player / day which is super unrealistic, so I’ll be supplementing this with my own money but the closer I can stay to that the better. Any help is greatly appreciated!
