I tried the Sunday champagne brunch at Wang's Place in Monrovia for the first time and thoroughly enjoyed it! They offer about 20 items including two kinds of soup and several desserts for $13.99 ($5.99 for children under 10). Their hot & sour soup is so good! They change a few of their buffet items each month, and if you're not a champagne drinker, you can get soft drinks instead. The Sunday brunch is from 11:00am to 2:00pm.
