We all know and love Spuyten Duyvil and Muggs, but I'm looking for places to grab a pint that won't require a ride on the L train. Where are the lesser-known gems in NYC that have an impressive beer selection (and I'm not talking about Yuengling on tap--I'm looking for the sort of place that offers microbrews, lambics, belgians, etc...). What is the atmosphere like--can you hold a conversation? Get a table? Do they actually clean their tap lines every so often so your beer doesn't taste like backwash (ugh, I had a rank one this weekend that was about three shades darker than it ought to be and had some sort of sediment at the bottom!)? I'd love to find somple place in South Brooklyn, but it's good to know what's out there city-wide. All suggestions and recommendations greatly appreciated.
