The first two times I went here with Rob, I didn't like it one bit! I could see their "drive-in diner appeal", but once when I ordered a hotdog there, specifying no relish, it came with all the toppings anyway and made me feel queasy :( This kind of thing upsets me since I am sensitive to green foods and seldom give any place [that ruined my order] a second chance.
However, I am happy to report that Inglewood Drive Inn has been bought under new management, renovated and cleaned up (I agree with Dinah G. on the ambiance thing). Their menu has changed slightly for the better, too. Now I actually enjoy it a bit more when Rob takes me there, and he can pig out as well. Yay!
P.S. I remember a child's elephant ride being installed there, so bring some coins if you're bringing kids with you.
