The Berkeley Lab cafeteria has closed to make way for a new welcome center, which will be constructed over the next few years and feature a new cafeteria. In the interim, food trucks and seating are available outside Building 91 (IGB) for lunch on weekdays.
A website featuring information on food truck menus and pre-ordering, other food options on the hill, and catering/food delivery options is here. If you are ordering food to be delivered to the Lab, you will need to request site access for the delivery driver in advance.
In addition, the Guest House next to the ALS offers food to go, and of course the Advanced Food Source outside the ALS control room in Building 80 is available 24/7.
