I've been to and enjoyed both restaurants. If you're looking for an unusual and fun atmostphere, you should try sci-fi... If you're more interested in the food part of it, I'd suggest going to Mama Melrose.
They are so completely different that it is hard to recommend one, Sci-Fi is certainly a lot more unusual, Mama Melrose is a very nice italian restaurant.
Wouldn't make a trip to MGM without having lunch or dinner at the Sci-Fi. The best burgers, onion rings, and chocolate shakes you will ever have!!!
Enjoy!!!
We have good food both places, but I think Sci-Fi is more of a lunch burger place where as Mamas has wonderful full meals. Since you are doing dinner, I do Mamas.
I have never been to Mama-Melrose but have been to Sci-Fi. DW and myself are talking about going to Mamas on our next trip and plan on going back to the Sci-Fi.
I would recommend Sci-Fi to anyone.
They have one of the best shakes around.
