I've driven down the 15 Freeway South on the way towards San Diego CA quite a few times this past year on the way to pick up Craigslist deals. I keep seeing the sign on the Bicycle Warehouse building (west side of the freeway on a parallel road), but never seem to remember to budget some time to stop in and see what the place is like.

Also seems like I've seen an advertising sign or another building with the Bicycle Warehouse name on it in San Diego proper, while driving on a West to East or East to West freeway.

What is the place like? What do they sell there? Is it worth taking the time to get off the freeway and see what's there?

You'll probably get better responses in the Southern California regional forum.

My simple google search tells me its a large LBS that sells GIant, Felt, Raleigh and Diamondback

Their advertised prices don't look any different than any LBS by me so I certainly wouldn't make the drive from LA. But if it's closer to where you live you might feel otherwise

Depending on what you are looking for there are many shops in the area... (Bicycle warehouse is mostly family bikes)

Jenson USA has their storefront shop up by the 91/15 interchange, off of Countryclub pkwy/sefras Road, and their warehouse is by the 215/91fwy. The warehouse has a walk up counter and a small show room.

and the guys at Stage2 bicycles in Murrietta are pretty cool. (They carry more high end stuff)

if you're going down towards San Diego, there's Bike Bling and the Trek Superstore in Escondido.
