Dinner for a hundred along HWY24 corridor

Organizing a dinner gathering for about 100 people for Sunday in two weeks, somewhere from Oakland/Berkley to Walnut Creek/Concord. Can only come up with East Ocean Seafood Restaurant in Alameda, Saigon Seafood Harbor Restaurant in Richmond and Uncle Yu’s in Lafayette. Don’t find much recent reports. Any other suggestions/comments? Chinese cuisine is not a requirement but they seem to have large banquet facilities. Many thanks in advance.

Lake Chalet can handle really big parties.
