Is sushi and SushiSwap the same?

I'm curious, could you clarify something for me? I've come across the terms "sushi" and "SushiSwap" in the context of cryptocurrency and finance, and I'm wondering if they're somehow related or if they're completely different entities? I'm trying to understand if sushi, the popular Japanese dish, has somehow made its way into the world of decentralized finance, or if SushiSwap is a unique project entirely unrelated to culinary delights. Could you shed some light on this for me?
