My parents are coming to town next week, and they're big art fans, so we were planning to go to the Sawdust Art Festival in Laguna Beach. Last time we were there, we explored the town a little, lots of nice restaurants and galleries, but we had a dinner reservation back in LA so we had to go. This year, I'm thinking of having an early dinner in Laguna instead of fighting traffic on the 405.
They're pretty adventurous, though they don't care for sushi. My mom's a limited vegetarian (she eats seafood, but no meat) and budget is mid to high, but not too high.
