Go on allearsnet.com and click on Dining. Then scroll down until you see the Easter link (on the left side) under Special Events. I don't know of any places that do a special brunch, but there are a lot that do special Easter Sunday dinners.
Highly recommend the Peabody on I-Drive - simply magnificent! Reservations are positively mandatory - well in advance!!! Get there before 11 am to see the March of the Peabody Ducks.
