Le Petite Cheval in Berkeley plays pony to the whole horse of Oakland's Le Cheval. Large airy spaces for sunny lunches. Good and cheap. I loved the crisp cool tofu salad. Today I tried 3 of the items from the array of dishes on display (3 item with rice for $5 - a bargain). Fairly well cooked, with the lovely and fresh green beans snapping to a total standout.
The Hummingbird Cafe north of campus offered small but reasonably priced sandwiches that were competently made. Enjoyed the cheap smoothies that were topped with some fruit -- a neat touch. Small and cheap portions allowed me to have a sandwich and a smoothie for around $5-6.
