There's a new stand at the Midtown Global Market - the Salty Tart Bakery. (It's in the space left by the Starlight Cafe - which is sadly missed - as mentioned here: http://www.chowhound.com/topics/513022 .)
I read somewhere (here? The Rake? The Strib?) that the Salty Tart is run by the founder of Franklin Street Bakery.
In the name of research, I had a coconut macaroon, and it was FABULOUS! Golden brown on the outside, meltingly creamy on the inside, and just sweet enough (that is, very sweet but not tooth-achingly so). Six bites of heaven for only $1.50. I hope they do well and stick around for a long time!
