The spike is gas prices in 2008 looks just like 2007.

Unless its different this time (thanks to the government stimulus program) casual dining sales trends are impacted by higher gas prices.

As a reminder, this is a small sample of what happened in the summer of 2007:
EAT lowered guidance in August.
PFCB missed in October.
CAKE missed in July
MSSR missed in September

I don't need elaborate any further...

Except, I should point out that the casual dining group is up 25% this year.
