Be prepared to spend a lot.
I was really excited to try Heritage after all the hype. We had a group of 6 on a Friday night. Didn't know they took reservations, so we waited in the bar area for about an hour. Tight space, not much waiting room. Only bar area tables are for "walk-ins" and most tables in the area seat 2 or 4.
Great cocktails, friendly bar staff. The Angostura Sour was well balanced and the Aviation was delicious. We ordered a cheese plate which was good (nice touch with honey comb), but overpriced. Our waiter was phenomenal! Super friendly and attentive without being annoying.
Similar sentiments with the food once we were finally seated. We ordered some of the more odd selections (trotters and escargot, octopus and fried cocks combs) as well as some not-so-odd (deviled eggs, pork belly and sashimi). All were pretty delicious, but felt like it was a bit overpriced. Few vegetarian options.
I'd try Heritage again. Definitely more of a special occasion kind of place, rather than a standard staple. Looks like they change their menu frequently, which is nice.
