The way things /used/ to be at Discovery Cove was that your one meal at Laguna Grill was free (hence why no prices listed), but snacks at the Beach Bar were extra. But from what I understand, they've revised that... so you eat free at Laguna Grill and at the snack bars all day.
We ate at Voyager's last year and really liked it, but they've changed the menu and we didn't enjoy our food last week. What once was a chicken salad in dressing served over lettace with a croissant is not a fast-food typle chicken Ceasar salad with those little croutons. Same price, lower quality.
We ate at the Hospitality Deli last year, most likely will eat there again, just don't see anything else on the menus that look good to us, might as well stick with what you know you like! Besides can't beat a free beer with your meal!!
