TLDR: Would definitely go again. Exceeded my expectations.
The short but sweet, very unique lunch menu had something for everyone, including vegetarians and vegans (maybe Gluten free too but I forget!) The culinary team at Harth makes an explicit effort to source locally and highlights their local farmers/producers on the menu, which I thought was a nice touch of transparency.
The fall squash items (delicata squash, and butternut squash soup) were perfect, and the flatbread was super unique and super delicious- imagine if a pizza crust and a croissant had a baby- that's the dough we're working with on this flatbread. Highly recommend.
The garganelle pasta was excellent- another locally produced item- that was reminiscent of whole wheat pasta, but without that tough texture, topped with a poached egg and eggplant/tomatoes, which the chef recommended mixing all together into a type of sauce I'd never had before and really enjoyed.
Rounding off the meal with the wood-fired cheesecake was a good call even though we were thoroughly full by this point (generous portions) because, again, it was a unique spin on a classic. I'd never had a crustless cheesecake before, and had no idea how you could do it in a wood-fired pizza oven, but alas, they did it! The woodiness of the oven slightly caramelized the top of the cake, then they throw on a strawberry compote of sorts to cut the richness. So good.
If you're over by the Capital One campus, or Tysons in general, I'd say this restaurant is worth the stop!
