Cunucu Terrace Buffet http://diviaruba.com/menus/cunucu_terrace.html is right there at the Tamarijn. The Pelican Restaurant at the Divi also serves breakfast and is a little bit more upscale, but I doubt the kids would care. Meaning it would probably not be worth it to them to walk or ride the golf cart down to the Divi just to eat breakfast (or lunch for that matter).
Same options as above or Pizza per Tutti, more details below.
Sit down ala carte restaurants:
The Red Parrot restaurant At the Divi All Inclusive
" features fine cuisine and attentive service for dinner only in either an indoor, air-conditioned setting or on the beachside outdoor terrace." http://diviaruba.com/menus/red_parrot_menu.html
We like all of the ala carte restaurants at the Divi/Tamarijn but the Red Parrot (above) is our favorite.
Ginger Asian-fusion restaurant "featuring air-conditioned indoor seating and chic modern décor, offers eclectic dishes such as Tokyo Beef Noodles, Mango Chicken and Vegetarian Tempura Mix."http://diviaruba.com/menus/ginger_menu.html
Unless your kids are "foodies" they will be willing to eat lunch and dinner and all snacks at "per Tutti". It is poolside so not far from the "action" and the food is very good! Speaking from experience of our family , for snacks, love the Mexican Fries, Onion rings and garlic bread. All are winners. Not to mention the pop corn and the self serve, soft serve ice cream.
If you told us we had to go to the Tamarijn and survive solely on per Tutti's pizzas, it would not be an issue. Their pizzas are delicious! My favorite is the one with all the veggies.
When we were there in December and traveling with 6 kids they were able to keep up with the demand.
Must have been a supply problem when you were there. Being an island with things shipped in, I am sure these kinds of things happen. At one time they made onion rings from scratch at the buffet one or two days a week, but at Pizza per Tutti they have used frozen rings. Now they do at both places. Frozen onion rings are better than none at all.
We agree with the mexi-fries... Pappi- one of the older gentlemen that help there gave us some hot sauce, that would curl your toes, but it was so good, you couldn't stop eating it, just had to grab another cold one to go with them...
