Finding Great Deals on Drinks

I came across DrinkDeal.com recently, and it's a great site. It makes it all too easy to find who's got the best deals on drinks on any given night here in NYC.

You can search by area, like Queens, Upper East Side, Chelsea, etc. You can also search by day of course, but I personally like the search by type of deal. They call it "Liquor Specials", you'll see it when you rollover the martini glass on the left side of the page, and you can search out places that have deals on shots, or "all you can drink" for example.

It's surprising to see just how many super cheap drinks are being served every night, and how you can find them all in one site. It looks like you can find a $10 open bar or all you can drink pretty much any night of the week. My biggest question is - what's the difference between "open bar" and "all you can drink"? My guess is "all you can drink" means they have rum and coke all night or something, either way it's good times.
