Zelicks is the only bar worth going to in San Marcos, TX. Period.
I love the atmosphere. I love the mixed crowd (college kids, locals, motorcyclists, hipsters, you name it, they are there). The first night I went there I ordered a whiskey sour in which the bartender said he "would like to see more whiskey in that, so take a big gulp" and proceeded to refill my already strong drink with a finger more of whiskey. It is so rare to find a bar in a college town that makes a decent drink without charging an arm and a leg.
Overall, this bar is perfect. It also happens to be a block away from my house so I don't think I will find a reason to frequent another bar as often as I find myself at Zelicks.
