I have been a lover of K&L Wines for years. I've always found their selection to be excellent and the only drawback was their location in Northern Cal.
Finally they have come to LA, and what a wonderful store. Helpful staff, no attitude or wine snobs here. You have a selection that cant be beat and prices which are some of the best in town. I think the best thing is that if you like a wine, they will normally have it in stock. So, it's not a "we bought a bunch of this for a special price and we can never get it again" thing.
Top notch, but be warned it's addictive!
Pros: Easy parking, fine seletion, good prices
Cons: Not in Pasadena!
