I think the food is awesome at TDR - lots of variety of both types and prices.
You can visit the official TDR web site and look up each restaurant - it describes what they serve in general terms: Tokyo Disney Resort
You can also visit the Disboards and go to "Other Lands" then the "Tokyo Disneyland" folder. I started a post there called "Tokyo Disney Resort Food". It shows pictures of different types of snacks and meals, along with pricing, that are available at both TDL and TDS.
