I was thinking the bar thing in HB looked great but if you bring the youngsters that might be a problem. My other idea was this place in Torrance where a bunch of really cool car clubs meet called Ricky & Ronnie's. Check out this link
www.rickyandronnies.com. Every time I pass by this place there are a bunch of different car clubs there. They also serve good food and offer ample parking. It's a bit of a drive for me but I'm in if you guys/gals think this would be a good location.
