i've also had the beef cheek poutine at haven gastropub in orange. the flavors in the gravy were good, but the gravy was too thick and they poured it over super thin shoestring fries which made them all soggy.
this is what ideal poutine looks like:
i do make poutine myself when i feel like putting the time in. i usually get the curds from whole foods and i think trader joe's has them, too. then i make the fries and the gravy homemade. it's a lot of work and cleanup and not really all that healthy (since it's not worth it to make small portion) so it's probably only a once a year thing for me.
