Question about a phrase

[torgosaves]

Hi! I have a phrase that I have been unable to find in the dictionary or anywhere for that matter. I've only heard it, not read it, so I'm not sure exactly what's being said but I'll write it anyway.

angattazou, or agattazou I know it means time to eat(because that's what the subtitle said), but I have no idea if this is how it is spelled or what. Is it slang please someone help me. If you want to hear it, it's the second line in the first episode of Cowboy Bebop. Jet says it to Spike. Thankyou

I think the phrase is 召し上がったぞ (meshi agatta zo)

Meshi agatta comes from Meshi agaru which means "to eat"
zo is a sentence ending particle which emphasizes one's opinion or judgment. It's used mainly by men.

Thanks. I think that this is the correct phrase; although he doesn't say "meshi". But I'm glad I now have the answer.
