Delaney BBQ is great - I probably have about 20 koozies from all my visits there when I lived in New York. Started going there when it was still order ahead by the pound and only open a few weekends a month. Love that place and would put it up against very good Texas spots.
Hill Country's meat is just okay, but the sides are good, and they have Blue Bell, which can be a Manhattan rarity.
Mighty Quinn's is decent. I'd put it above Hill Country, but not close to Delaney. Still kinda irked that they wouldn't give me free bbq when my name is Quinn.
