I didn't take any pictures while in Discovery Cove. We were there this past December. Breakfast was a bunch of different options, I remember the standard eggs, bacon, sausage, I believe some sort of french toast sticks, a breakfast casserole, fried potatoes/hashbrowns/home fries, and then grab and go items such as fruit, pudding, jello, cereal, milk, breakfast pastries.
Lunch was about 5 hot options ranging from hamburgers, chicken tenders, some sort of fish dish, roasted chicken, then some side items like french fries, and then the grab and go area was fruit, salads, desserts, pudding, jello.
The snack options varied throughout the kiosks around the park. Most had a big basket on the counter filled with individual bags of potato chips, granola bars, pretzels, etc. and served warm soft pretzels. Some had popcorn (if I remember correctly). One or two had ice cream (chocolate/vanilla in cups like you get from the grocery store, not soft serve or hand scooped). Alcoholic slushies (like pina coladas) and alcoholic drinks (like beer, vodka/lemonade, margaritas [don't get too excited these two come in the world's smallest plastic cups
]) and I believe a non-alcoholic slushie (like a slurpee) and then soft drinks. Some have coffee/hot chocolate too (we actually got hot chocolate when we were there because it was 60 degrees outside and the Grand Reef is cold!). We were pleased with all the selections. I mean, nothing we had was amazing, but it was all edible and at least tasty.
