For high school graduation dinner, my son wants to go to a sushi restaurant. This will be on a Saturday evening after 6:30PM and we'll be driving from Menlo Park. The four of us (2 adults, 2 teens) hope to go to (reserve a spot?) a great restaurant within a 1/2 hour drive. Though everyone in our family likes sushi, we don't normally visit sushi restaurants. All suggestions, tips are welcome!
