not sure - why not just check with restaurant direct? But we did notice that Californians in general seem to prefer to eat earlier with most restaurant dining rooms being almost empty by 10pm

Fridays and Saturdays usually are for late dining. I recommend you search opentable.com for a time that should work for you. 10:30PM is probably the last seating for even the ones open until 11pm. Frascati's last seating is showing 9:00PM.

Thanks for your replies, I guess we're just used to eating later! I'll take a look at Opentable.com....
