Can you do RS pub crawl in Venice if you don't drink alcohol?
of course, all the spots will have mineral water they will be glad to charge you for. You could also get coffee. Some places might have soda, although that might be iffy. The main purpose of the crawl is to eat cichetti and have a grazing style meal.
Lori, I don't drink and I ordered a lemonade (ie: Sprite). There's no faux paux about not drinking whether in Italy, England or whereever
