The 1 pound of crab legs can it feed two people or we need to get thec1.5 entree

Go for it!

I'd order the 1 lb just for myself, if it's to be my dinner. Most of that weight is in the shells. If it's to share as an appetizer or snack, go for the 1.5 lb so you both get enough.

Yes 2 people can share

I would get the 1.5lb entree

It's ok for 1 person

1.5 entree for sure. Not a up sell. The extra .5 is worth it.
