Do yourself a favor, and do NOT order the cous cous. We ordered it upon recommendation from our waitress and we didn't like it one bit. It was way lemoney. I'm not sure what cous cous is really supposed to taste like but it didn't appease me. She found out we didn't like it and ended up taking it off our bill. I guess it pays to be honest in a semi-high end restaurant.
I'm not a big fan of chain restaurants but I really wanted to try Houstons. The prime rib we ordered was alright, and I had the Hawaiian Rib Eye which was TO DIE FOR! The marinade on it was perfect but the only thing was that it somewhat charred the meat since I'm guessing there was sugar in the marainade and that burns quickly. Our dishes came with a HUGE baked potato that I couldn't even finish.
Overall, I would revisit Houstons again for their Hawaiian Rib Eye and perhaps some sushi rolls.
