Question: are lo mein noodles the same as spaghetti?
Answer: The one thing every source I could find agreed on is that it's made with egg-and-flour noodles. Spaghetti usually refers to a particular shape of noodle, usually made of durum semolina without eggs. The only characteristic Spaghetti share with the noodles used in Lo Mein is that they're sort of long and skinny.
