I really enjoy the colors and the feel of the game so far. I think centering the text and the characters more to the left would read as more polished in future versions (on my pc they are not centered, and it gets ruined in full screen mode). It is very interesting to make the route choices based off of what food you ordered!
Another suggestion is to add different text variations to the flavor text words, such as the sizzling bacon. I feel this could add to the charm and personality of the game you've already added so far!
