You don't have to be a foodie to understand the Rum House is overratted.
I'm from BR and have lived in NO for a few years. I've been to many restaurants. Rum house is good. I like their brisket taco's. It's a different feel from the standard mexican restaurants. The food is geared towards a more mexican/caribbean infusion of cultures. I find it good, and me and my fiancee' go there whenever we are in town and are just touring around the city.
I love the pretentiousness of you NO die hards here.
Is it the best place to eat in NOLA? No.
Is it a good place to eat in NOLA? Yes
They do what they do very well, and are rewarded for it. Yes some of it is atmosphere, but isn't that what about 75% of sales from a restaurant comes from? The draw of a nice atmosphere? You're not going to go eat good food in a rusted out, moldy crackhouse.
Their food is good and the atmosphere is good. If either of the 2 were not good, then they wouldn't get business. Plenty of restaurants sprout up and die because they only had 1 or the other. You have to have both to stay successful in the Restaurant biz, which is a business that has one of the worst success rates.
