Jeff Gerstmann is anti-mayo. Our lord has spoken!
Jeff and the giant bomb staff don't read these messageboards.
Mayo is disgusting unless it's incorporated really well into food. If there's even a bit of excess mayo on a sandwich, like where you can taste the mayo without the accompanying flavors of the sandwich, it's just gross.
I do like it on top of an omelette, but that might only work with Japanese mayo.
