I have a full set of Portmeirion Botanic Garden china including many of their accessory pieces.
While I personally prefer plain white dishes, these belonged to my husband before I met him and he just loved the pattern (he had actually chosen the set himself, not by a previous wife) and they were insanely expensive! I continue to use them (while he has since passed away) for obvious sentimental reasons,
I do have some very inexpensive Corelle luncheon plates that I use a lot for just that since they can go right in the oven or microwave.
The Portmeirion is quite durable though I made the mistake of putting a dinner plate in the CSO and the temperature must have been too high because the plate broke in half $$$!
Fortunately I have eleven more of them. That's where the Corelli earns its keep.
