Jigg's doesn't have a website or a Facebook account. It barely has a Yelp profile. It's the best dive bar you've never heard of. And yet it's almost always packed with people. Owned by the same family for 63 years, its customers are among the most devoted in the city. They're there day and night swapping stories drinking listening to a jukebox that's packed with a lot of Motown and R&B. It's also one of the few remaining half-pint bars in the city.--Erik Maza
