Every Tuesday night 5-9 PM, downtown Huntington Beach (AKA Surf City USA) closes down Main Street for "Surf City Nights". FREE admission, live entertainment, Farmer's Market, international food booths, arts and crafts for sale, and more! As you can see by the Kodak Moment here, the little kids trying to pop large bubbles were amusing. Several restaurants will validate for parking (Tip: BJ's will validate even if you don't eat there). This is a great place for tasting different foods for only $3 each! The pupusas from El Salvador and empanadas from Argentina were yummy! Again, this is every Tuesday, but there is a special Halloween Fest on Saturday (see website for more info).
Approximate cost of creative date idea = $15.
Actual value of the cheap date idea = Priceless.
