I've noticed quite a bit of nurseries have trouble correctly labeling and marketing both Stromanthe sanguinea and the Ctenanthes oppenheimiana. If you say it has a thinner leaf, and has a more overall delicate look, I think it's actually the Ctenanthes.

Have a look online in a google image comparison--you'll find comfusion in some calling one the other, etc.

and, they both like bright light (no direct sun after 9 am) fretile moisture-retentive soils. They are perennial, but in cold weather they will stop growing, leaves brown or in a frost, die to ground and come back in APril/May.

Poiu,

I searched as you suggested. I still think it looks closer to a stromanthe sanguinea, but it is a more delicate stromanthe. The ctenanthes look more closely related to calatheas? Anyway, I haven't found the correct id yet. I don't have this plant, just saw it and am thinking about getting it. Thanks for your suggestion.

What color are the leaves? Is there any patterning on them? What about the flowers?

Kind of hard to ID it without more details.

The leaves are a deep green on the top and a wine burgundy on the undersides. The stems are the burgundy color as well. My recollection is that the leaves were about 6-8 inches long and about 2-3 inches wide. They occurred every few inches up the stem. I wish I would have taken a photo. Sorry! Thanks.
