I ended up going to Johnny's Hamburgers with two friends of mine who are familiar with Scarborough. Apparently Johnny's is a landmark. I had never heard of it before! We went at night and the place was full (it is very small) so we had to wait a long time for our food. The food was relatively cheap and very good. I enjoyed reading all the newspaper articles on the wall and talking to one of the staff members about the history of Johnny's. If it wasn't so far I would definitely go back!
