Cedar and Shattuck. This is, hands down, my favorite lunch place to eat in Berkeley. It’s a sort of nouveau-French place (with real French people) with a lunch menu priced just right at $6-$8. The menu rotates every month to take advantage of the fresh veggies for the season — you can download it from their restaurant. Their distinctive octagonal cardboard boxes can be reused for a discount on subsequent visits, but I’m sure that the more creative can find new uses for them.
The appetizer list doesn’t change every month — I recommend the potato puffs, which are small scoops of dry mashed potatoes deep fried with an aioli. Delicious! And for dessert (if you want to splurge), go for the bread pudding. It’s heavenly.
I can’t recommend this place enough, so go already!
