What is the meaning of mos in Japanise?

Actually I doubt it's a Japanese word, seeing as how it would have been spelled "Mosu" if it was. But even if they English-ified it it would still be ambiguous, since Japanese has tons and tons of homonyms and/or homophones X3

I hope those guys are better than McDonalds or that place next to Akihabara station I can never remember the name of. If there's one thing the Japanese suck at on an epic scale, its cheese burgers =D Even Planet Hollywood in Ueno was a pale imitation of the real thing. But then again, I don't fly to Japan to get cheese burgers so its all good. I eat a lot of Sushi when I am there. Can eat my fill for about 1500y. Here in Tucson I cant get out of a sushi place for anything under $40 these days.

They are way way better. I'm going to miss them when I leave lol X3

Ans I love how cheap food is here! I can eat three meals a day for less than 1,000yen if I'm careful X3
