We loved it on all three of our last trips (December 2008, August 2009, and August 2010). It has become a must-do for us!
We have never ordered the pasta or parmigiana dishes, though.
It's interesting, because the pasta and parmigiana dishes seem to get panned at Mama Melrose's, Tony's Town Square, and Tutto Italia. It almost makes me wonder if Disney can do pasta or parmigiana right. I have never tried these items at Disney, so I don't know. But if you read reports, that is what seems to disappoint people the most.
I always order the calamari, the anitpasto, or the mozzarella and tomatoes for our table. We have tried the wood-grilled tuna and the strip steak for entrees. Both were outstanding, especially the tuna.
I love Mama Melrose's!
