Your "In and Out" pages are fun, Dell! I'm from NY and they didn't have In & Out Burgers there. I'm not a fan, but know that people who come from somewhere that had them missed the chain before it came to AZ. I miss 2 chains from the east coast--Friendly's and Carvel! Culver's recently came to the Phoenix area. I'd never heard of it before, but apparently it's very popular in the Midwest. I guess we all have our favorite local chains.
A little survey: Scrappy friends--what's your favorite chain in your area that you'd miss if you moved and they didn't have one?
In answer to this, my fav restaurant here in Phoenix is Texas Roadhouse.
