(E)ating at the counter by the window allows you to experience your sandwich standing up. The au jus is plentiful to say the least (and you can order more if you like), so don’t be surprised if you drip onto yourself. But even if you stain your lily white shorts, a trip to Brennan and Carr is well worth it. After a couple of bites, the soggy bread mingles with and eventually fuses to the soaking wet roast beef. About half way through, the sandwich becomes one delicious, unified being.
