In steamy weather, the ice cream at Taste the Tropics (shown above during a paint job some years back) gets runny very quickly. On one visit it began melting so fast and furiously that I couldn't manage a picture, and the only takeaway was a few soursop drops on my Merrells.
Generally it's better not to dilly-dally. Shown: grayish Guinness Stout atop slightly paler Irish moss (two scoops, currently $2.95), already dripping into my hand; pistachio-peanut (a single flavor); banana atop Irish moss. The bright banana ice cream, it may surprise you, was less flavorful than its companion, made from a seaweed that grows along rocky coasts on both sides of the Atlantic.
Also shown: a closeup of the awning, listing a few of the 20-some varieties available on any given day. Under a slightly different name, the next to the last is much better-known in New England, but you can try it on Nostrand, too.
