Roti Canai Or Roti Pratta

I read the food menu at the mamak restaurant where located near with the hotel. I mean in Geylang, Singapore.

When I see a word that pratta, I think that it's a special bread. The price is $1 (RM2.43). My friend tells me that roti canai is same as  roti pratta. I don't know.

This word is in my mind. Okay. I order roti pratta. I see roti pratta.

Oh, yeah! What the bad size? Roti canai is cheaper if compare size between roti canai and roti pratta.

Does it looks bad? However, I don't feel so full after eat roti pratta. I don't order one roti pratta else.
