We discovered the best food in Uluwatu too:
BLACK ROSE: Outstandingly fresh, delicious and cheap Vietnamese food. Go for the chicken salad ($2.50 USD), stay for the incredibly nice owners. And they serve tiny Dutch pancakes! We went almost every other day. I feel so strongly about this place that I did a (glowing) Trip Advisor review. And I don't do Trip Advisor reviews.
THE CASHEW TREE: Killer Pitaya bowls. Perfect smoothies. Massive salads. Gorgeous open air set-up. Fast wifi.
NALU BOWLS: Nalu bowls (smoothie bowls topped with fruit and granola) were my favorite discovery in all of Bali. Get one from the little hut outside Single Fin then enjoy the view over Uluwatu reef. Nothing beats a sunset Nalu bowl. Nothing.
BUKIT CAFE: Cool (both aesthetically and temperature wise) interior (most places in Bali don't actually have an actual interior -- you're always just entirely or partially outside being baked by the sun) with delicious chia seed puddings.
LANDS END CAFE: Conveniently situated down the road from Morning Light Yoga and serves French Press coffee which is the closest thing you can get to a good old fashioned, filtered American coffee.
AYU'S: Giant classic breakfasts (eggs, bacon, toast, fruit bowl) in a brightly colored cafe run by a darling Balinese couple.
