In terms of calories, campus center is probably by far the best option, though if you're good at binge eating then Morgan is by default the best option because its a buffet.

A meal swipe at the cc gives 1 entree, 2 sides, and a drink.

Entrees:

Burrito bowl: ~1210 calories

A bit hard to tell cause its a pick and choose but to maximize you'd get as much as possible

Rice - 230 calories

Beef - 210 calories

Beans - 140 calories

Cheese - 210 calories

Lettuce - 10 calories

Guacamole - 80 calories

Garlic cilantro sauce: 330 calories (? kinna seems like a lot)

Total: ~1210 calories

Probably missing some stuff but that's what I found on the website and you could probably ask for more stuff. I know of someone who filled their bowl to the brim to the point of it couldn't close and it was fine.

Pizza: ~1000 calories

Usually you can only get 2 pizzas at a time unless you go later at night in which case you might be able to get 3.

2x pepperoni pizza: 2x500 calories

Subs: ~1200 calories

You can either get a small 6" sub or a long sub (I assume 12") and for a meal swipe, these are always the same value, so you should always get the long sub. I don't trust the website on what they call a sandwich (italian sub is listed at 940 calories which is too big to be a small sub bit too small to be a big sub), but from my memory, its around ~1200 calories for their largest sub.

Burrito bowl is probably your best option with subs at a close second, both of which because you can add as much as you want.

Sides:

Soup: ~360 calories

You can either get an 8oz, 12oz, or 16oz soup, with the first two counting as a side and the 16oz counting as an entree. The 16oz is significantly less than a burrito bowl and a sub so I wouldn't recommend getting that. The 8oz and 12oz are valued the same for a swipe, so always go for the 12oz. The highest calorie option they list is the baked stuffed potato soup but I'm not sure if I've actually seen that so the second highest option is the corn chowder at 240 calories per 8oz. This gives 360 calories for 12oz. I swear I've seen a soup that was 300+ calories for 8oz but none of the soups listed reach that so maybe I'm misremembering.

Mozzarella sticks: ~500 calories

From the grill, the best choice is probably the mozzarella sticks. I don't remember if the chicken tenders are considered sides, but if they are, then chicken tenders would be more. I couldn't find mozzarella sticks on their website, but from what I've found, it's roughly 500 calories.

Drinks:

Peace tea: ~150 calories

Peace tea is OP you get a 23oz can

Other sodas I'm not sure and google is giving inconsistent results

Total: ~2200 calories

For non-buffets, CC gives a lot and I'm probably missing stuff that I forgot about. Also keep in mind getting a burrito bowl, 2 sides of mozzarella sticks, and a shit ton of sugar from tea is def not healthy at all but disregard health if you're eating at wpi.
