like others pointed out already, there seems to be a few glitches:
belt always moving / guests on the right eating dishes on the left / dishes randomly disappearing …
and I don't think there is a loosing condition, right?
nontheless, it sounds really promising, and the graphics, sound and movement seem really polished. I made it till day 12 and 500 points, until I saw the counter to 99. I think some variation in later days would be in order (pun intended).
