Stumbling in to Oaxaca on Easter Sunday, I was worried there wouldn't be a restaurant open. The first place we came to was Catedral, and it was so good we came back again before leaving the city. The pork ribs in mole verde are crispy on the outside and melt-in-your-mouth, fall-off-the-bone wonderful on the underside. The zucchini greens soup was also delicious and filling (I had trouble eating my main dish after the soup because it was such a large bowl and came with arrachera on the side!) Would happily return!
