AmbulanceDriver pretty much took the words out of my mouth, except I have a preference for Power's over Jameson, and not the 12 year with the frequency with which I drink it.
For summer drinks, you can't really beat Bacardi Big Apple & Sprite or Disarrano & Ginger Ale with a splash of grenadine for color. Or a creamsicle if I feel like buying ice cream, which I never do.
As for beer, Guinness at bars, Hefeweizens at home, preferably Franziskaner Hell when I can find it, or Paulaner when I can't.
That said though, I now live in the great state of Pennsylvania, and our liquor laws make as much sense at New Jersey's traffic laws, so I drink beer with much less frequency than I once did. For a quick overview, we can't buy beer anywhere but bars or beer distributors, and bars can only sell up to a twelve pack. The closest bar to me charges $8 for a six pack of American cans like Coors & Michelob. Beer distributors can't sell anything less than a case.
So, instead of living in a normal state and being able to buy a few six packs of different varieties, I have to spend way too much to get what should be cheap beer, or commit to 24 of the exact same thing.
