Although I only gave them two stars I have to admit I have been to McFadden's many times in the last 3 years. Most of the time my frequent trips had to do with continuously having friends win the ""free"" bar giveaway (have to admit, its not hard to win these).
I think their marketing campaigns are great, however, the cleanliness and college frat party feeling tend to make me hesitant on actually going to McFadden's on a regular basis. Looks can be deceiving as well. Just because they have a bathroom attendant does not mean their bathrooms are something to rave over. I would actually vote their bathrooms as one of the worst in D.C...however, as I mentioned before, they do have some amazing drink specials on a nightly basis.
Pros: Great deals each week
Cons: Can tend to feel like a frat party
