I don't think Whataburger can be found outside of Texas. I'd put them in the mix.
may be found in: AZ, NM, TX, LA, AR, OK, MS, AL, GA & FL.
Another Texas-based burger chain, Mooyah
, has also been metastasizing like crazy ( www.mooyah.com
). They are opening in Bahrain, Kuwait, Dubai, and Qatar!
Their original "business plan" was to totally "rip-off" Five Guys
before the Guys got around to expanding into Texas. Their first store in Plano was a Five Guys with a different sign - right down to the store layout, color scheme, menu, fries, bulletin board, and 'free' peanuts-in-the-shell; even their web-site was identical! I wrote Jerry about this and he got his lawyers after them, but even now - six years later - you'd swear you were in a peanut-less, milkshake-serving Five Guys.
