Right now, my favorite are salt and vinegar chips. I do like the baked lay's chips or regular barbaque. I'm not a fan of of the kettle cooked.

This thread does remind me of what my British interns used to call french fries... chips! Side note, I spent so much time with them during my internship that I actually said 'chips' instead of french fries. Some good times!

So for British 'chips', my favorite are shoe string french fries like from McDonalds or I love sweet potato fries! Oh, if I go to CA, I love Chick-fil-a's waffle fries.
