Yes...every Pats game the Orange County Patriots Fan Club meets at the Fox Sports Grill in the Irvine Spectrum. Check them out here: http://ocpatsfans.pbwiki.com/
These are good places to watch Patriots games in the LA area:
Santa Monica
Sonny McLean's
2615 Wilshire Boulevard
Santa Monica, California 90403
310-449-1811 http://www.sonnymcleans.com/
Probably the greatest Boston bar on the left coast.
Hermosa Beach
Poop Deck
1272 The Strand
Hermosa Beach, CA 90254-3547
(310) 376-3223
From the Hermosa Pier its just a little bit north right on the Strand.
Also in Anaheim at National's Sports Bar, there is a decent sized group of pats fans. It's Off of Orangewood & State College blvd across from Angels Stadium, close to the 57 fwy and I-5
If you go to Sonnys in Santa Monica I suggest you get there before kickoff as just about every seat in the place is almost always reserved. But it's a great place to watch a game with a free raffle of Pats schwag at half time.
