Katz's
Katz's, on Westheimer Road in Montrose, is a 24-hour New York-style deli and diner serving sandwiches like the Klassic corned beef alongside burgers, breakfast plates, and a full bar. It's the most-reviewed sandwich destination in Houston by a wide margin, open around the clock every day of the week.
What people praise
- Round-the-clock availability makes it a reliable late-night option
- Wide menu with something for nearly every craving, per reviewers
- Cheerful, knowledgeable staff called out repeatedly
- Fried pickle spears and burger options praised alongside the sandwiches
Worth knowing
- One detailed reviewer describes overly crunchy bread and overcooked chicken tenders on a delivery order
- Pricing runs higher than a typical quick-service sandwich shop
Our take: The most-reviewed sandwich spot in Houston by a wide margin, and the only 24-hour option on this page. A safe bet any time of day, though it leans more diner than classic deli.
