Came here with the family over the holidays after hearing my brother sing the restaurant's praises. Since I follow a vegan diet, I called the restaurant a day in advance of our reservation to let them know for the purposes of accommodations. I ended up ordering a vegan version of the six-course tasting menu, and I was blown away by the quality of the food and the care put into my dishes. Whereas most restaurants might veganize a dish by simply removing the animal-based ingredients, Heirloom took the extra step and substituted ingredients that demonstrated the chefs' know-how. For example, when my family got grated parmesan I their salads, I got grated walnuts on mine. That is to say: they make vegan parmesan the same way I would! The rest of the dishes were also of high quality and I left quite pleased that we visited this restaurant. If I'm in the area again I'd love to return for another helping.
