I just ate dinner at Maiz for the second time and I thought I'd report back. I enjoyed my meals there, but I have to say, I was surprised to find the walls covered with extremely positive articles from Chicago Mag, the Trib, etc--I didn't feel quite as enthusiastic about my experience.
The aspect of Maiz I like the most is that the menu is focused on a la carte street food from all over Mexico. I've seen the various foods around Chicago at restaurants, stands, Maxwell, etc, but never all in one sit-down place. The menu features typical items like tacos, fajitas, sopes, huaraches, but also street foods that are hard-to-find at restaurants like elote/esquites, various types of tamales, empanadas, gorditas...
All of the masa dishes are made in-house and they specify on the menu when non-homemade flour tortillas are used.
Unfortunately, they didn't have take out menus, but the list was fairly extensive. They also have Mexican hot chocolate, Cafe de olla, atole, a nice variety of desserts (including crepes with cajeta--goat milk caramel).
The ingredients are very fresh and they offer great choices for toppings--shrimp, al pastor, barbacoa, huitlacoche, nopales, lots more. They have several choices for vegetarians. But I felt some of the dishes were a little light on the seasoning. The al pastor meat was tender, lean and accompanied by nice pineapple chunks, but it was a bit lacking in flavor. I have to say that for nearly every dish, I was left wishing for a bit more oomph.
Everything is offered a la carte. The menu seems inexpensive at first glance, but the portions are quite small. Our tab for 2 for a 'light' meal with one beer (served Michelada style with salt rimmed glass, lime, on-the-rocks) was over $40. The interior is very attractive and the presentation was nice, too, but the restaurant is pretty informal. If we had eaten a full meal, we could have easily spent another 10-15 bucks. Coffee and hot drinks were about $4. I think horchata was $3. Given the great options for Mexican food around Logan/Humboldt, I felt the prices were a little high.
During both trips, I was waited on by the same woman who seemed to have a Russian accent. She was very friendly, if a little bossy. She forgot to bring one of our dishes and when we mentioned it, she replied "Why don't you see if you can finish everything you have on the table and if you're still hungry, I'll bring it out for you." There was something slightly amusing about being waited on by a Russian woman at a Mexican restaurant in a heavily Latino neigborhood, but she was quite knowledgable about the menu and we appreciated her guidance about what to order.
Overall, I had two very nice meals there. Maiz is an especially nice option for vegetarians and for people who are somewhat health-conscious (everything tasted very light and non-greasy) but I'm not sure I would rank it among my favorite Mexican places.
If anyone is heading over there to check it out, keep in mind that it's cash-only.
