I've been to the brunch at the Visual Arts Center in Munster several times (not my choice, believe me) and it's awful. The tables are squeezed together and the food is terrible. I've been to North Pond, Ritz Carlton and Four Seasons for Easter brunch as well and the Visual Arts Center is nowhere close in terms of food quality, level of service and atmosphere so I would strongly advise against going there.
Last year, we went to RL and it was delicious. There is no buffet--you order off of the menu--but we all enjoyed it very much. So if you're not tied to a buffet, then I strongly suggest it.
