I'm not sure when it started but Libertad is now open for Sunday brunch.
http://www.libertad7931.com/brunch/Found out quite by accident as we were trying to find a brunch spot for today in the suburbs, and OpenTable showed them as having 11 AM tables. [I mention this explicitly since some restaurants have a love/hate relationship with OpenTable...we would not have otherwise known about Libertad's brunch since it also hasn't been mentioned here yet]
We showed up about 10:40 AM and about half the restaurant was occupied. The staff were friendly and accommodating for our two children and the high chair was out in a flash.
My older daughter had the french toast - because she's a bit picky, we had it served plain, with the roasted pineapple ice cream and the fruit on the side. Agave was also brought instead of syrup. The compote listed on the menu never came but was not missed. My daughter proclaimed the French toast to be excellent, though she wasn't a huge fan of the ice cream - it was a very light flavor and I think she wanted something stronger. We also ordered the yogurt parfait, which was pretty (sorry pic didn't turn out) and ended up doing well with the agave. Mrs EdB60035 had the huevos con chorizo - scrambled eggs, sausage, black beans, and queso fresco, served with tortillas. It had a nice spicy kick and was given a thumbs up. Me, I had the winner plate of the meal, a ticket to heaven for only $8 - the omelet, which included bacon and brussels sprouts, topped with shaved manchego cheese and chunky potatoes.

The omelet was perfect, a little crispy, definitely flavorful in every single bite. I only recently have started eating eggs so to clear my plate on this one was a real testimonial. It wasn't chewy at all, and the sprouts had a nice crispness still in them.
I would have loved to have tried the bloody Mary, but needed a clear head for the day so opted instead for a guyaba - mango, guava, banana, and lime juice.

This was really tasty as well. Mrs. EdB60035 tried the Mexican hot chocolate, which had a nice spiciness to it in addition to the rich chocolate flavor.
I expected we would want to order yet one more dish but this foursome satisfied us. As a bonus, though I'm not exactly sure why, they didn't charge us for the French toast (it was listed on the check but with a 0 next to it for price), so it was an inexpensive brunch as well.
