Tasty Greek yoghurt with great quality ingredients but $4.87 for a small is expensive for what you get. The menu was very confusing at the start and it wasn't very clear to passers-by what they actually served. This was recently fixed and there is now a large board with clear prices on the wall behind the counter.
I would consider Astarte for breakfast as a treat, in my opinion it's too expensive to go there regularly, regardless of the quality of the ingredients.
