Actually, PBR on tap is not that bad. If I'm drinking on the cheap, I'll go with a PBR, on tap or not,
Really, I like all types of beers, but it depends on who is brewing them. Dogfish Head makes decent beer, but the prices they charge are pretty ridiculous. I've had much better beers for cheaper. Right now I have two favorite IPAs: Odells IPA and Brew Free or Die by the 21st amendment brewing company.
I also really, really like the New Belgium brewing company out of Colorado. Unfortunately, they do not distribute to the east coast. Try the Mighty Arrow, 14 Below, or the Ranger IPA as they are all quality. Their flagship beer, Fat Tire, is not very good in my opinion.
Another good Colorado brewery is the Left Hand Brewing Company. I really like two of their beers: Sawtooth Ale and the Milk Stout. I actually went on a beer tour one day and stopped by here. It was awesome. I tried 30 different beers that day.
As far as wines go, I'm less picky. I like Pinot Noir generally. I'll go with white or a blush wine if it will compliment the meal. Otherwise it's always red.
I don't drink liquor as much, but I do have my preferences. I like Tequila. Unfortunately, I have yet to find any decent tequila in the city. Unless the bottle says it's 100% agave, it's actually vodka flavored to be like tequila. My favorite brand is 30-30, which, like my favorite beers, you can't find in NYC. Stupid.
I also like spiced rum and whiskey, but I don't often purchase them.
