Chowhound from NYC spening Sat. evening in the city of brotherly love. Staying downtown, but need a chill, low cost if it's an option, casual, american cuisine dinner. Female companion not adventuresome diner and writer does not enjoy portentious dining. In fact writer does not like "dressing up" outside of work. No tie and jacket. Advice where steak, seafood, or other american cuisine inside an environment that fosters drinking is needed. Thanx.
