Crumbs Bake Shop
Crumbs has just opened a location downtown Chicago. They are certified kosher by 2 agencies as listed on their website. I wasn't able to find either one of these 2 on teh CRC website and was wondering whether they are reliable. Their cupcakes look PHENOMENAL!
We are specifically forbidden to discuss the reliability of hechshers here, so you might want to ask your LOR. I've never heard of the second hechsher, but the first is not universally accepted in New York.
As always with these questions, you really should ask the Rav YOU hold by. Mine has a split decision on the two agencies you mention.
