Two very different experiences, both excellent!
Love Blue Zoo, I find the menu imaginative and so very tasty! The restaurant decor is fun as is the ambiance. We've seen it from very busy and bussling to a bit quieter, neither affected the service, but we do eat very late while on vacation, so that may be a consideration. They have wonderful drinks and appetizers. I have an opbsession with the tuna tartare, it is so good, I also love the beet salad! The parmesan and garlic fries, sinful! I would not consider them a seafood restaurant, though they do offer some dishes,the menu is really quite varied. The past entrees I've had are no longer on the new menu (black sea bass, and a pork dish), but the new fois gras appetizer has my name on it in June!
We've eaten there 3 times (6 of us, 2 teenagers incl.) and we have only raves! I have yet to make it to dessert, too full!
Il Mullino, how I missed this restaurant for so many years, I don't know. They have a, can't think of the name but it amounts to a cold antipasto platter with a wonderful selection of dried/cured salami's, prosciutto, mortadella, roasted peppers, mozzarella! It's meant to be shared but just give me crusty bread and I can eat that alone. The fried calimari, so tender! Here comes the hard part, deciding between the carpacio of beef or tuna, can't be done, order both! Veal Saltimbocca, only had better in Italy! My son had the veal chop, it was a thing of beauty! My friends had the Carbonara and the fish, I think snapper. The Carbonara will be my next selection. We had peas with pancetta and shallots as a side, I make these now and take full credit for the recipe! Didn't make it to dessert that night either!
We discovered Il Mulino last year, and yes we will eat there again!
Both are very expensive, at least for my pocket, but compared to typical Disney TS fare of similar pricing, the cuisine at both can justify the price!
Recommend both!
