I don't know how I didn't discover this the last time I was in Granada, but a great way to eat cheaply and try a lot of different foods is to order a drink at practically any establishment. You will not only get your drink, which will be about $2 if it's wine, but you will get a free snack (tapa) with it. It's practically getting paid to bar hop. OK, so maybe bars are serving their day-old bread, but it's FREE, and often times delicious, and most time something to do with ham.
