Having enjoyed Falafelito in Condesa, we heard about this store opening much closer to where we live. We have now been here around 10 times and have had excellent food every time.
The staff are courteous and patient when your Spanish is not perfect. At the times I have visited, they seem to have a problem sourcing pitta bread and currently only offer it in wraps, which I personally prefer.
Due to being able to eat it inside, I much prefer the Coyoacan branch to the Condesa one, especially in these wet summer months. It is also just a few minutes walk from the Zocalo, meaning that during the summer, you can also enjoy it in one of the most beautiful places in Mexico City.
