Hi,I live in LA and am getting married in DC in September. I'll be buying my own alcohol....what's the best avenue to go here? Costco? Trader Joes? Local liquor stores? The wedding is in the NW area near American University. I'll be in DC in May for a visit and am thinking of buying the wine and beer then, even. Approx 70 people expected, half of them Irish so I need to buy more alcohol than normal!
