I bought one with bacon for $2.99.
My Breakfast Toaster turned out rather nicely, and had a bit of a homemade feel to it with the way the eggs were fried.
The bacon provided good coverage but was only occasionally crispy. The flavor was the standard salty smokiness.
The cheese melted thoroughly, which is always nice.
Overall, Sonic's Breakfast Toaster was a pretty competent execution of the standard breakfast staples. There wasn't too much or too little or any of the three main ingredients and everything turned out fairly well.
