Yuck :o)

For a really good beer, try Krug Brau Pilsner or St. Georgen Brau Pilsener

Clearly we have different beer tastes - I'm not exactly a big Pilsner fan, sorry. :)
Here are a list of my favorites:

Guinness
Black and Tan
Brooklyn Brewery Black Chocolate Stout (really heavy, but good)
Sam Adams Black Lager (a very underrated beer)
Sam Adams Brown Lager (though mysteriously they stopped making it???)

On occasion I'll drink a Sam Adams seasonal beer (though I don't like the regular Sam Adams). I used to drink Dinkel Acker and liked it. The only light beer I'll touch is Amstel Light (it's very good when it's fresh). When I hit the Microbrewery pubs in Manhattan I go for the house porters.

And I do find either Corona or Dos Equis to be good dinner beers.

I used to like McEwans, but I don't think you can find it now.

So that's about it. I'm pretty predictable when it comes to beers - two dark rich cold ones with a peppercorn burger and onion rings, and I'm a happy boy.
