My wedding was there.
I'm a wedding planner for the newly renovated Hotel Shattuck Plaza located in Downtown Berekeley and we have beautiful ballrooms and banquet space perfect for weddings 200 people or less. We can host both the ceremony and reception on-site. We also have options available for rehearsal dinners and guest accomadations. If you would like me to email you pricing and information or setup a time to stop by for a tour please feel free to contact me directly. :o)
