Ice cream
You'll be able to find ice cream at many an eatery in Tallinn, although locating an actual ice-cream stand while wandering about seems to be a bit hit and miss - and availability also seems to change from year to year. Your best bet is to hit a supermarket such as Rimi or the 24-hour shop if you prefer your creamed-ice on the go.
