Lee's is a very awesome, interesting, and educational place. It's really a lot more than just a place that sells beer and stuff, as they have such a great variety of different kinds of libations that you walk out knowing a lot more than you did walking in!
On my last trip here, I needed to buy some beer and bottle of rum for a thing at my house. I walked out with different beers, rum, vodka, and mixers... all for a pretty good price, too! See, they have so much stuff that you can't just walk out with one thing! It's awesome!
Plus, I've learned of different brands/types of alcohol through that store. I walk in thinking "I just need some Captain Morgan" and walk out with a bottle of Sailor Jerry, which is really good, too! It's to expand your horizons, you know.
Also, they sell mixers. They sell Coke, margarita mix... all that stuff. It's easy, quick, and has a great selection for a low price! Lees = Win!
