re: Best and worse national casual dining chains.

In responding to a thread like this it probably helps to keep in mind that: a) I'm not comparing chains to locals and most of the chains I've eaten at have at least something that is likeable and "ok" (so stay in the safe waters). That said:

Best: Zea's, Copelands, Carrabbas, Outback, Cracker Barrel, Rudy's
Worst: Olive Garden (but salad and bread sticks are still good), Red Lobster (cheddar biscuits and grilled fish are ok).
