Cassidy's Mesquite Kitchen - Houston, Texas

Chase Erlich

Cassidy’s Mesquite Kitchen, nestled in the downtown Houston tunnel system beneath the McKinney Place Garage, is a hidden gem known for its outstanding mesquite wood-grilled burgers and delicious onion rings. The menu caters to diverse tastes with options like juicy ground sirloin burgers, mushroom Swiss burgers, and even vegetarian choices.
What truly sets Cassidy’s apart is the warm hospitality of its owner, who makes every customer feel welcome and valued. This personal touch enhances the dining experience, making it a favorite spot for me and many others.

Seems like a mom and pop shop. Very friendly service (that I haven't seen much of lately which made it notable). Food was as expected, not outstanding, but everything tasted fresh. Price was definitely on the lower end of things which is always a good point. Very happy with everything I got today, so will make it a point to go back and try something else on the menu.

Best place to grab a bite for lunch in the tunnels. Big variety of food choices, highly recommend their grilled chicken sandwich, the bread is amazing. The staff here also goes above and beyond every single time I visit. The lady at the cashier truly cares about her customers and you can tell through her interactions. This place is amazing and I truly enjoy eating here.

Order at the counter and sit anywhere in the big open dining area and wait for your number to be called. Self-Serve soft drinks and tea. Service was quick and the food was tasty.

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.

I've walked pass this spot many times and decided to try them today. I ordered appetizer spicy fried pickels and they were the worst fried pickles I've ever had. The pickles and batter was not fresh. The batter was falling off and you can see and taste that the cooking oil was old! They also gave me two cucumbers that didn't look good either. Yuck, threw it away. What a waste of $7.58. Never coming here again. I'll stick to Texas Roadhouse for the fried pickles. I will post pictures.

The Thumbs Critic

? The burgers are good. They use a sweet bread for the buns.
? They were a little slow to get moving and take orders at the beginning of the lunch hour.
? The iced tea tastes a lot better than most other restaurants in Houston.
? I saw someone's baked potato, and it was HUGE.
? It appears that ordering via an app will save you time. I ordered my food to go at the counter, but it looked like people ordered via DoorDash after me, received their orders faster.
? Not the establishment's fault, but I arrived 3 minutes early and sat at the closest chair nearest to the counter to rest from the mile hike here... and some guy cut in line. He didn't even offer an apology when it was obvious that he cut in front of me. I guess next time, I'll be one of "those customers" who stands at the counter and rings the bell before lunch starts.
