The food is good, I agree. But they don't serve alcohol so they can't qualify in any best brunch contest. Shade was one of my favorite brunch spots when i lived down there.
It's not a brunch, but the mimosas at El Jarrito in Katy are very tasty. They have the typical Mexican breakfast fare (chilaquiles were da bomb) along with their full bar.
I only really like brunch when it's a buffet. I haven't been to a good brunch buffet in Houston even though I've lived here my whole life.
Houstonian is always nice. Goode Co. Taqueria has a great breakfast menu served until 12:30... ouisie's you can't go wrong with if you want something nicer. Backstreet Cafe is also pretty good.
Try Baba Yega in the Montrose area, but get there early. I haven't been in a while, but their Sunday brunch was delicious for a buffet. I also loved the waffles and chicken wings, or the catfish and gritz at The Breakfast Club. Also, get there early or wait in a long line. Only open I think from 7am-1pm? LOVE Hugo's on Westheimer, Goode Company and Backstreet Cafe since it's close to home for the headache drive. I also remember having a chicken fried steak at Ouisie's Table, along with shrimp and gritz and it was outstanding. That was about a year ago though, no idea if they're still open? Edit- DM knows his brunch! I guess Ouisie's is still open. I might hit that place up this Sunday.
