IIIT Guwahati has two canteens, one in the hostel building and one in the academic building. 

• The canteen at IIIT Guwahati is average. It is just like the ones that are common among all the government colleges. It is not much developed and high standard, however, it serves its purpose. 
• The canteens at both the girls’ and boys’ hostel are allowed to operate till late at night. The canteen in the academic building is operated from 10 am to 11 pm.
• There is also a food van available that delivers food directly to the hostel.
• The mess service at IIIT Guwahati is just fine. It serves three-time meals; breakfast, lunch, and dinner. 
• There is also a tea facility for an extra charge. It is not included in the mess charge and has to be paid separately. 
• The breakfast and lunch served are usually vegetarian. At the dinner, the students are given an option to choose between a vegetarian special item and a non-vegetarian special item. 
• The taste is good and the food is of satisfactory level. The non-vegetarian food served is really good.

Both the mess and canteen are not high profile but are satisfactory. Now, tenders are offered, thus making a competition between caterers which is a positive sign for improvement and better service.
