I also can't comment on the HOB at DTD, but we have gone to the Gospel Brunch numerous times at the HOB in Chicago. It's something that our kids always look forward to when we visit! And we definitely have plans to go to the Gospel Brunch at DTD when we're there in Dec. My understanding is that HOB Gospel Brunches are pretty consistent at each HOB venue.
In Chicago, it runs about $43 per person, but we normally get a private Opera Box because my DS is Autistic and we'd rather not risk sharing a table with someone, in case he were to have a problem. I think it's $38 for general seating and $15 for kids under 12. The seating is made up of a combination of long picnic-type tables and round tables.
You are seated with others, unless you have tickets for a private box. For those who may be Pooh-sized, the chairs are a folding-type and appear to be a bit flimsy. I read on another post -- or somewhere, I don't exactly remember where -- that if you would prefer a different chair, the servers are very discreet and will move you to a different area or provide a different type of seating.
There are two different seatings for the brunch; in CHI, it's at 9:30 & 11:30. The earlier seating, which we go to, is less rushed and -- we think -- a better performance.
The food has always been phenomenal! It is made up of several different buffet areas. One is waffles with a ton of different toppings, including fresh strawberries and fresh whipped cream. There is an area with roast beef, fresh crusty and artistry breads, bacon, sausage, etc. Another area for a made-to-order omelet station. Then, as I recall, in another room entirely was a long (maybe 40' long!) table with exotic salads, spicy gumbo, jambalaya, paella, fruit, shrimp, etc... Coffee (excellent), tea and OJ is included. Oh, and I forgot the enormous dessert area with cheesecakes, brownies, fruit tarts, pecan pie, etc...
The HOB itself is in incredible venue and is decorated in such a way that it provides a very "stereotypical" rural/folk art/creole/southern ambiance. You could actually spend all day just looking at the folk-art pieces and artful phrases in abundance throughout the entire HOB. The entertainment is wonderful and very moving. The Gospel singers are absolutely passionate in their vocal and physical worship of God and have amazing voices. They really incorporate audience participation in a non-cheesy way as well.
So yes, it is expensive, but is an extremely entertaining and moving way to spend a Sunday morning in worship...
One note: If your children are sensitive to loud sound, the Gospel Brunch is VERY loud.
HTH and have a great time!
Update: I checked out the website for the HOB in DTD
(Click Here) and it is quite a bit cheaper than CHI and it doesn't appear to have as large a variety of food. Still looks great though!
