Chelsea Brewing Company on the West side. If your in the City on Friday nite, you have to get to Brooklyn Brewery for happy hour. That is if you referring to New York City
I have been consistently disappointed by the Heartland Brewery over the years. I have gone to several different locations, and the bere is mediocre compared to most othe rmicro breweries. I'm not saying it sucked, just that it wasn't "hey this is some good beer, I'm really enjoying it".
The last time I went (in April) I tried a sampler of 8 beers. Only the Kolsch was good, the others were just fair.
