When I was young, my friends grandpa had a basement bar where we would occasionally watch sporting events. He had two morbidly obese cats. Those cats were incontinent.
I bring this up because this bar looks like it was slapped together with slightly less aplomb than this childhood memory of drunk old dudes, and the smell of cat pee.
Mullen's doesn't really bring anything new to the table. Literally. I feel like my lobster roll had been sitting there for days. My wife ordered a pizza, and I just don't feel like commenting on it, other than to say it was wet.
The bartender was a nice guy, but there really isn't anything crazy that he needs to make and the beer selection is sparse. This actually reminds me of some of the terrible college bars that I went to in Oakland. Oh, and the lights are really bright for some reason. And nobody wants to see my ruddy face three beers in.
The overall sense is that very little effort has gone into this place, and in a street filled with bars, that seems like a pretty epic mistake.
