First off, don't expect gourmet food at Trinity, but do expect enough to get by. The three dining centers—Mather, the Cave, and the Bistro—are all operated by Chartwell's, which means that they aren't in competition with one another (hence the mediocre food). Mather, the main cafeteria, has a wide variety with vegetarian selections, a grill, and specials each night. The food is cooked for the masses, though, and thus can be rather bland; however, you can always find cereal or a homemade bagel with good cream cheese. The Cave, a smaller cafeteria with booths and couches and located in the basement of Mather Hall, is fun for lunch; the food is greasy and good, with fresh pizza, delicious curly fries, and a salad bar. The Bistro, on the north side of campus, is by far the best choice for a nice meal. You can get wraps and fresh-blended smoothies and great hot soups on snowy days.
Mather Cafeteria has huge tables that can each seat about twenty and smaller tables for a more intimate group of seven or eight. It is a fun place to meet up with friends each night for dinner, and to socialize. The Cave is great for a quick meal between classes. You can also spend hours sprawled out on one of the stuffed chairs or couches in the cave, nibbling on curly fries and drinking coffee and studying. The Bistro has delicious smoothies and a nice atmosphere, with flags hanging from the ceiling and beer on senior night.
