I can't walk into a Walmart but don't have a real problem with Target. I can't think of a chain restaraunt that I've ever had a good meal at, including places like Legal Sea Food.
My approval goes to:
Most fast-food places, honorable mention to Carls Jr & In-N-Out. I had White Castle once and can't see how people refrain from puking while eating that shit.
My all-time favorite chain store or restaraunt is Costco! LOVE it.
