Hi Angelica, Those are two great restaurants and my family has enjoyed dining in both of them!
Coral Reef (
HERE) offers a beautiful atmosphere, complete with a very large aquarium. The food is delicious and we thoroughly enjoyed our meal.
Tutto Italia (
HERE) also has pretty surroundings. The Italian food is superb. It quickly became one of our favorite restaurants, and my husband rates it as one of his top 4 to dine in at Disney.
I don't think you can go wrong with either choice, and it really depends on whether you prefer Italian or Seafood more. We are big fans of Italian food, so if I were to choose, I'd pick Tutto Italia.
Hope this helps and that you enjoy your vacation with your boyfriend,
Kaylene
