Robeck's will soon be back to the area.
I live near Merrick & there's a sign over by CVS next to a Wine Store that has a sign saying "Coming Soon" Robeks.
Have you tried the other Robeks in Plainview-Oyster Bay Road
There's also Madison's Smoothie Cafe on 2793 Jerusalem Avenue, North Bellmore. They also do supplements for 0.10 cents more. A bit more on the pricey side although I think. You can check their menu online. $4.50-$5.85 depending on what you get. An acai version is $5.85 [I know the owner's of the place]
I can't wait for Robeks to come back since Rita's in Bellmore on Merrick is never opening again & I need my Acai or pumpkin fix [What about Jumba Juice?]
