While we technically go to both, I haven't been to Costco in quite some time. Sam's has my chips, but I think Costco has the better "food court". I was shocked to see the hot dog and drink combo still on the menu. I heard Costco wasn't getting rid of it for "healthier options". I guess that's only in trial districts or whatever. While I'm a vegetarian, Daisy loves the hot dog and drink at Costco. I love how inexpensive the thing is.
