Cassidy's Mesquite Kitchen

Cassidy’s is a breakfast and lunchtime spot in the tunnels frequented primarily by people working in downtown Houston. They offer several kinds of breakfast tacos for breakfast (until 10:30 am) and a lunch menu that includes salads, quesadillas, burgers, and seafood (with an emphasis on catfish). It has a relatively spacious dine in area compared to most restaurants in the tunnels, though the place is a bit haphazardly decorated by random Houston jerseys interspersed with old Life magazine covers and photos (with almost all of the above being poorly framed and many showing water damage). I stopped in at around 12:30 pm to find the place with several people but not overly busy. I ordered the bacon cheeseburger and made it a combo with fries and a drink (onion rings, and sweet potato fries are also an option in lieu of regular French fries). My order came out relatively quickly, and I was impressed by the quality of the food. The burger, while not being absolutely amazing, had a good flavor, with the fresh sourdough buns being of particular note for their freshness, taste, and texture. The fries were also delicious with a fresh texture that got the mix between crispness and sogginess just right. Additionally, as I dined, one of the managers or owners came around to ask how everyone’s food was, which is something I do enjoy seeing. That said, and subpar decorations aside, the main detractor for me was price. The cost to upgrade a burger to a combo is $5.50 more than half of the cost of the burger itself. I can’t ever remember a restaurant charging so much for fries and a drink. While I did enjoy the fries which were of good quality, they don’t justify such an enormous up charge, and is not something I think I would pay for again. So I can say that I will definitely return here in the future to try out other burgers as well as items like the tacos, quesadillas, and catfish, and I do recommend it as a decent lunch spot. Unfortunately, the shoddy decorations and combo prices means it only warrants 4 stars, rather than a full 5.

Excellent place that has vegetarian options as well

I had the mushroom Swiss burger and onion rings. The burger was good; the meat wasn't anything special, it's flavor didn't really stand out, the toppings were great, and the sourdough bun was awesome. The meat was a little more dry than I normally like. The onion rings were great! The service was fast and friendly. There was no line when I went, but my lunch was a little bit after the typical lunch rush. The restaurant is pretty dimly lit, which is a little annoying, and the bare concrete floors don't quite have the industrial look that they were maybe going for.
