There are people who will chase after foods in search of "the best" - at least to them - and I can understand that. I'm interested in "the best" chocolate, ice cream, milk shake and gelato. There are a few other things, but these are items I'll mentally catalog and celebrate when I find a new level.
L'Arte del Gelato in Manhattan's West Village at 75th and 7th. I tried five flavors (two of their way too small "medium" cups) and Sukie tried two along with one of their drinks. I'm clearly going back, but can recommend:
Vaniglia del Madagascar
The Madagascar Vanilla was particularly wonderful as was the Chocolate mocha. It isn't often that I can praise a vanilla, but this one is worthy. I'm told their olive oil is excellent, but I didn't try. Sukie loved their Affogato all'Arancia, which is fresh squeezed orange juice with lemon sorbetto and a bit of Campari.
Very spendy and worth it. The next time I'm tempted to skip lunch and just order a pint, which is a comparative bargain at $10.
Now Grom has to be sampled to see which is really the best, but so far I'm loving this one.
Some things you have to take into your own hands... for milkshakes the bsst I've had are those I make. I'm not particularly gifted and I suspect most simple don't pay enough attention to detail.
