I grew up in Texas. I ate Mexican food twice a week in New York and even once in a while in Paris and it's really not that easy to find a good Mexican meal in Merida. Josh is from San Diego and had Mexican food daily and we agree that Mexican food in Merida is very hard to find.
We go to a filthy dive called Reforma once or twice a week and eat chile relleno or mole but nothing else. This season also the Chile en Nogada is very good according to the carnivores in my life. Christmas decorations are up year round and the chihuahua named Paris Hilton is an excellent and glamorous hostess. $
Frida's chef/owner is from Mexico City and when she's in the kitchen the food is very good. When she's not in the kitchen the food is inconsistent and the service is never up to par. $$$
Pancho's is as close to Tex-Mex as you can get but not close enough for me. Here the service is the best thing about the place but if you're young enough not to know better you might like loud music and imitation cheddar cheese. $$$
The tacos of Ana Sabrina in the Santa Lucia Park are as close to real Mexican food as you're going to get and I'm there almost every Sunday. $
The new Apoala in Santa Lucia Park is a Mexican restaurant with many of the flavours of Oaxaca updated and it's the place to eat your first dinner in Merida as you may want to eat all your dinners there as there is nothing better to the north, south, east or west. You can read my review on the other blog but basically my advice is order appetisers and then order more appetisers. Good Mescal menu.$$$
...and not far from centro off Avenidas Reforma and Colon is one of my favourite lunch spots since I became a vegetarian. Platos Rotos cook is also from Mexico City and offer and extensive menu that changes daily which makes it easy to go several times a week and not get bored. It's home made comfort food in a very informal setting. $
