Went to my favorite tourist trip/bar in Manhattan yesterday, McSorleys which is cash only (which is common) has only two beers (dark and light) and they give you two mugs of beer when you order one. I love this place, though I'm sure many NYers give it a pass, but I really would like to hear of other places with severely limited menus and/or kind of weird service offerings? (not looking for weird decor)
Another good one is Dan's Cafe in DC, where they give you a bucket of ice and mixers so you can make your own drinks. Any others out there?
