My FI and I looked at venues theis past weekend and i decided to put in my 2 cents. we only went to 3 places.
House of Broel - I don't hear much about this venue on the boards. it is very formal and was a bit stiff for our tastes. It was quite pretty and right on St Charles. It was the least expensive of anywhere I got quotes from. The front area was divided into an entryway and 1 room on each side of that and I think it would only work well for a small wedding that was less then about 50 people.
Rosy's Jazz Hall - We really liked it but it is only for quite specific taste. It is very New Orleans-y. If you want something grand and elegant and super romantic it is not the place for you. It does have a fun, funky vibe. We are booking it for us because my FI was actually excited about it and he is one of those guys who wants as little wedding pomp as possible.
Wax Museum - I though it was a nice space and much more versitile than Rosy's but in turn that meant that it would be much more work and cost into making ot what we want. The location is great but no good area for getting ready if you want to do ceremony and reception in the same place. The price is quite good compared to most of the areas we researched. I didn't mind the "creepiness" of the museum but it does have some dark exhibits.
Hope this helps the girls researching venues
