Don't go during restaurant week.
We'd been saving this place for a special day as it's pretty pricey. When we finally went (not realizing it was restaurant week) they had a limited menu and our waiter was pretty up front about the fact that they normally do better.
My fiancé ordered a mozzarella salad appetizer that contained exactly two pieces of mozzarella. Our cocktails didn't live up to the reputation either. Both were almost straight liquor and my fiancé's tasted like Vick's.
Our entrees were very bad. Neither of us got more than halfway through. My fiancé's fried chicken had minimal chicken meat and my eggplant lasagna didn't seem done. The eggplant was tough and not very flavorful.
We ordered dessert (because it's a package deal with restaurant week) but took it to go because we were so underwhelmed with the whole experience. We haven't tasted it yet.
The point of restaurant week is to encourage people to try new places and find new favorites. I don't think Heirloom will be winning any new customers this week, which is a real shame because the farm-to-fork idea is so cool.
