To be honest, I never look at individual prices on a menu. I could not tell you what a burger cost there. That said, it just that whenever we have gone to GP the bill always seemed out of whack for what we got. Just my imagination? Possibly, yes.
Now that I think about it, it probably seems more expensive because they do not accept TIW. So, it is 20% more than places that do take it.
I am not really anti GP. We visit on a regular basis. I do wish the menu had some more options however.
