Maerdwyn,
you beat me to it -- I was planning on starting a similar thread but instead of just naming favorites, I was going to try to get people to give the pros and cons of the stores in their area.
Sounds like a good idea to me
Here's my evaluation of Bay Area, CA stores:
San Francisco:
Gamescape San Francisco
333 Divisadero St.
San Francisco, CA 94117
(415) 621-4263
Pros: Great selection, good sized used section, in store gaming.
Cons: few discounts, used section is invariably expensive compared to other area stores, including the other Gamescapes. Staff is somewhat indifferent, IMHO. Parking is tough.
Peninsula:
Gator Games & Hobby
4212 Olympic Ave
San Mateo CA 94587
650-571-PLAY(7529)
http://www.gatorgames.com
Gator Games is, as stated above, my favorite of the whole area, and is located in San Mateo on the Peninsula. Pros: Great Selection, well informed staff, constant discounts, twice-weekly game nights, lots of parking and the owner is a great person who will work to find anything you're looking for. Cons: no dedicated in-store gaming space, used section is somewhat small (but cheap!)
Gamescape Palo Alto
465 S. California Ave.
Palo Alto, CA 94306
(650) 322-4263
Home of my first campaign when I moved to the area, I have a soft spot for this store.

Pros: A good selection, a decent and inexpensive, but shrinking, used section. In Store gaming, with lots of terrain avalable for use. Staff is friendly and helpful. Adequate parking.
Cons: few discounts, staff is Very RPG oriented, and not all that helpful with miniatures games or board games, in my experience.
North Bay:
Gamescape
1225 4th St
San Rafael, CA 94901
(415) 457-8698
Nice, well organized store. Pros: In-Store gaming, very good selection, painting classes, excellent used section, with reasonable prices (except of 1e hardbacks). Cons: Few discounts, staff is well informed but no overly helpful IMHO, hard to get a parking space sometimes.
Ian's Games
301 Georgia St #A12
Vallejo, CA 94590
(707) 552-7127
Nice sized store in an ugly pink building.
pros: Good selection, especially of older RPG's; entire store is always on sale, usually 15%(GW 10% off), some items deeply discounted; Some Used stuff; Ian is very helpfu, plentiful free parking. Cons: Only Open Fridys (2-6)and Saturdays (8-5)
East Bay:
Epic Worlds
Castro Valley Blvd
Castro Vally, CA USA
510-733-2585
Small store, with a very good used section. They usually have a booth at area cons.
pros: Used section is huge. In store gaming.
cons: hours are irregular - call before going. Selection is limited for everything except GW. Staff is only marginally helpful. Used section is huge, but very expensive.
Games of Berkeley:
Large store in downtown Berkeley. I basically echo eveyone else's comments about GoB.
Scenario Game and Hobby
37120 Fremont Blvd.
Fremont CA 94536
510-792-9333
http://www.scenariogame.com/
Really large store thant's been around for decades, but whaich was taken over by eminent domain and will be demolished to make room for a mall.
Pros: Massive selection of all things hobby and scouting related. Had a whole bunch of old school minis (T'Char the dragon, anyone?) until I bought most of them

. Really large instore gaming room. Helpful owners, dedicated to the hobby.
Cons: They may re-open in the new mall, they may not.
South Bay
Neutral Ground
San Antonio Plaza
Mountain View, CA
Pros: Great in-store gaming, good GW selection. Right next to San Antonio Hobby Shop, where I buy all my terain-making supplies, paint, and brushes.
Cons: RPG selection isn't great, and has been shrinking.
D&J HOBBIES & CRAFTS
16 SAN THOMAS AQUINO RD
CAMPBELL CA 95008
Pros: Another really massive store, dedicated not just to gaming, but to RC cars, model trains, and general crafts.
Pros: Good selection, Only place in the bay area to get Old Glory and Foundry Miniatures in any quantity, as far as I know. Usually there are several 30% off bins near the front of the store. Lots of parking
Cons: Staff is hit or miss (especially in the gaming dept.), few discounts on current stuff. Minis are all behind glass doors, and not all that organized, making it a bit hard to browse.
There are other stores in the area, but these are the ones I visit enough to comment on.
Edit: Added my comments on Neutral Ground, after being reminded by Gizzard.
