Mama Melrose isn't great Italian but if you stay away from the Italian staples dishes like the ones that have tomato sauces or the Fried Calamari, it can be terrific. Go with the most American sounding dishes they have on the menu, like the steak or the pork chop, stay away from their attempts at Italian sounding dishes.
'50s Prime Time has much better and consistent food for what they are attempting to do which is classic Americana style retro comfort food from a bygone era. Every dish I've had there has been great. I've had the chicken pot pie, the fried chicken, and the stuffed pork chop and all delicious. And the decor is straight out of Leave it to Beaver and the wait-staff all act like they're in a timewarp. It's quite the experience. Portions are HUGE, too, and they DO get on your case if you're struggling to finish your veggies or have elbows on the table.
