I've been here a few times now and have had no problem ordering a burger w/o bun. The burgers are less traditional so be sure to ask if unsure what's on some of them.
The bartender (the only person we could see that was working in the front of the house) was a complete jerk! He was very unapproachable and very short with all his customers, therefor I did not feel like asking any questions, let alone gf questions. I asked for a wine menu and he barked back, "we have a red or a white". He snapped at my boyfriend when he asked for butter and just said, "No!" my boyfriend replied, "excuse me?" and he said, "we don't have any!" We would never return because of this and we are both in the service industry. This was our one and only bad interaction in NOLA and we ate out every meal. There are way better places to choose from, don't bother with this place.
