The other day before starting out diets, my wife and I noticed Sheridan's Frozen Custard had opened (went up very fast) on E Mill Plain in Vancouver, in the Cascade Park neighborhood. Decided to give it a try. It's the only franchise in the NW for the ice creamery. Everything is made on-site constantly.
Their menu is extensive, overwhelming really. (The attached link is to their online menu.) And oddly, they have a driveup window and a takeout window with a big standing area (covered and outdoors), but no place to sit.
The ice cream is good. It's dense and not gooey like some other places, eg, Cold Stone. I like both textures fine, but I know many people prefer this less gooey texture. The flavor is strong, though.
They really only have two flavors, chocolate and vanilla. Their emphasis is on sundaes and "concretes". A concrete is essentially a blizzard, like at DQ.
Anyway, if you're in the area, it's probably a good ice cream alternative.
