Finally made it up to Momcorn, in the company of the friend who had originally told me about it. Fortunately, having a friend who is willing to share meant I could try more items.
This place is great. The fun was compounded by the fact that, because my friend is a regular, the owner, Sergio Rivera, came over to chat and tell us more about his food.
For drinks, the corn-based choices were between atole and chicha morada (they have several non-corn drinks, including soft drinks, tea, and coffee, but I was there for the corn). I've had atole a number of times in Mexico, so I went for the chicha. It was tasty, sweet-tart, tinged with cinnamon, and (as the name suggests) deep purple. Sergio brought over an ear of the dark purple corn used in making the drink, to show that the color was natural.
I ordered a cup of pozole, which was spicy (but not brutally spicy) and flavorful.
Sergio recommended the quesadilla, which was outstanding -- made with cheese, epazote, and serrano chile.
Next we had sopes topped with meat and avocado and two kinds of tamales (rajas and chicken with green chile).
We finished the meal with a warm, sweet empanada filled with guava paste and cheese.
Sergio enthusiastically related that the ingredients are locally sourced and all natural, nothing is frozen, everything is made from scratch. He related (no doubt because he would have no way of knowing the level of experience of this pale nordamericano woman) that some customers got tears in their eyes when they ate some of the specialties he produces, and would tell him his food was just like their grandmother's. (I love it when people are excited about what they do.)
Sergio also said (and I figured this would appeal to this group) that they have what is, in essence, a "secret menu" -- which, he explained, means that they had to limit the menu, but that doesn't limit the chef. If it's from Latin America and involves corn, they can probably make it. Just ask.
This is probably not worth the trip north if you're in the city, where Latin cuisine is fairly available, but if you're in the northern suburbs -- or if you're heading to Wisconsin and wondering if there's anything to eat in Gurnee (Momcorn is not far off 94), or heading for Great America (which is very nearby), this place is a good option.
Momcorn is small and casual, with yellow and orange chairs and booths, walls decorated largely with photos of corn, situated in a strip mall next to a Subway. But it's definitely not ordinary.
