Never heard "pasta" used to mean just spaghetti...around here pasta refers to any Italian style noodle-like product, lol. There are lots of pasta dishes on Mama Melrose menu.
Anyway, the latest Mama Melrose menu I've seen had spaghetti served with two dishes --the Spaghetti Fra Diavolo (spaghetti with seafood) and the Chicken Parm. is served over spaghetti. The other pasta dishes included penne pasta, pipette pasta, ravioli, and rigatoni pasta. I don't recall ever seeing just meatballs/spaghetti on the Mama Melrose menu and we've been going there for several years. I think Tony's in MK has the spag/meatballs.
