The first time I went to Oyamel, I had their tacos. One word, superb! The second time I went I had the 'Costilla de cordero a la barbacoda' (lamb). While I have a special place in my heart for lamb, both the service and the lamb were surprisingly underwhelming on my second visit. I'm not sure which was more disappointing, but both service and taste play a huge role in my dining experiences... Still, the presentation was eye-catching! I definitely want to go back and try their brunch menu.
