Oh man! I am a musician by trade (I like to treat it like a small business, which is why I read HN) and have performed at Four Courts in Arlington several times - great atmosphere, beer selection, and staff. Who doesn't love a thick Irish accent? In fact I'll be one city over later that night performing in Alexandria around 10pm. How long do these meetups last?
On the other hand, you've disregarded the possibility of continuing to browse after doing three things (or stopping prior to three things).
