I love fries, I've never been able to stand onions in any form. Onion rings always smell really good to me though, but once I bite into the slimy onion under the tasty fried shell.. no thx
Definitely has to be fries. Sweet potato fries are amazing, I'd even go as far as to say they're my favourite food, with just the right amount of seasoning.
Also recently went to Five Guys for the first time when my partner was visiting, and damn, those fries! I do like onion rings too, but they're not very popular here and I think I've only had them a few times. Here the crisp / chip (ones in the packets you buy individually, not with actual onions in them) are way more common and popular.
