Ok so I sometimes go here to watch Texans games. It is billed as a sports bar but really only has one decent size TV downstairs. Still I love the place. The bartenders and the crowd are always so much fun. The prices are decent on beer and the deck is nice to sit on and people watch on the weekends. One big bonus(and I mean big) is they have their own parking lot. Parking is at a premium in the area and Zone 504 is one of the only places with it's own parking. They do sell food but it is very limited. Great fun crowd and bar. Only thing I would like to see is either a bigger flat screen or maybe a couple more throughout the bar
Review Source:I love the 504. It is our favorite hangout in Kemah. There is always parking, because of their private parking lot next door, they have cheap and good drinks and the atmosphere is great. The bartenders are quick to recognize you and they can even make some pretty good cocktails.
Downstairs is usually busy and crowded (especially on Karaoke and live music nights), but if you want some more space to talk and relax, you can go upstairs or outside where it's usually calmer. The outside is also excellent for 4th or July fireworks watching, especially now with the new upstairs patio.
The only reason it doesn't get 5 stars for me is that people smoke there, although I recognize that it does add to the atmosphere. It's also not as bad that you really notice it when you're there, but your clothes will smell afterwards. So if you don't mind that, I would give it 5 stars.
