A forewarning I am a bit of a grammar Nazi.
         "His parents had given him so many instructions they made his head spin" I don't know if there's anything grammatically wrong with this line, but something about it bugged me. Perhaps "The many instructions given to him by his parents made his head spin."
         The first line of the third paragraph ("Behind him a cave") is a sentence fragment, this can be fixed by adding "sat" or "lay" or some other verb between "him" and "a".
         The line "Tall and slim" in paragraph five is also a sentence fragment, which can be fixed by adding "He was now" in front of "Tall and slim".
         I think "accountancy" should be "accounting" when referring to the class. Accountancy is the profession, but the class itself is almost indefinitely referred to as "accounting."
         Also in paragraph seven the semicolon after college should be a comma, I believe. The second half of the sentence, when left as is, is also a sentence fragment, so replacing the semicolon with a comma should fix that.
         Paragraph nine, there should be a comma after "seaweed"
         Then in paragraph ten, technically "the mermaid" works, but I think "a mermaid" would be better, as this is the introduction of the mermaid, whereas before it could've been any fantasy creature.
         In paragraph eleven there should be a comma after "return."
         Paragraph twelve-- add a verb in the phrase "her voice alluring and seductive." I personally think "sang" would sound good there. Like "her voice sang, alluring and seductive."
         Paragraph sixteen combine the first two sentences by adding a colon after "passed." Otherwise the second is a sentence fragment.
         Also in paragraph sixteen there should be a comma after "no drive".
         Paragraph twenty two there should be a comma after "soft drinks."
         "Philistines" should be capitalized in paragraph twenty three.
         After "fact" in twenty three, there should be a colon, not a semicolon.

         Hi, anujmathur ,
I've decided to review your short story. Just as a disclaimer, please remember this is not my piece, but yours. Any suggestions I offer you do not have to take. The final decision is yours.
         FIRST IMPRESSION: I'm pretty sure that this is the first chapter in a fantasy sci/fi book. Or I have extremely misinterpreted everything. My concern with this is it moves too fast. I mean we go from writing to cooking to aliens in like four paragraphs (not counting dialogue.) I'll explain more when we get to the plot section.
         PLOT: As I said in the impression, it moves way way way too fast. Slow it down. I would suggest not introducing Morphy until the third chapter at least. If I were doing this (and this is your work so this is just my opinion) I'd probably spend the first chapter talking about Vikram's normal life. Where does he live? Who are his family and friends? What does he do right now? The second chapter would be about getting the job in the kitchen and working. Maybe before anything else he notices strange things about the place. And then you can introduce the whole alien thing.
As for the alien thing, interesting. Morphy seems almost childlike to me. Especially the way you depicted him. Something just screams "child" to me.
You have an interesting foundation that gives you a lot of options of where you want to go. It could be a fun little kids tale where Vikram explores the universe. It could be a tragic drama as Vikram and Caesar try to keep Morphy hidden, like ET. It could even be a sort of space war. Morphy missing some of his memory adds mystery that I'm sure you can use.
         CHARACTERS: Like I said above, we don't know much about Vikram. Nothing of what he looks like, how old he is, what he does, anything other than trying to get rich. The Chef is the same way. Morphy is probably the most developed character, although he could use some work too, like where he's from, stuff like that.
         SETTING/IMAGERY: One thing: give a date. I thought this was in present day until you talked about 2054 being in the past, which confused and startled me.
         GRAMMAR/TYPOS: When you make a quote that would end in a period like "Throw the ball, Jim." and you want to put "Sally said." after it you put a comma in place of the period, like so "Throw the ball, Jim," Sally said. That is consistently missed throughout the piece.
         OVERALL SUGGESTIONS FOR IMPROVEMENT: Slow down. Roller coasters don't go straight up, they go up gradually.
Thanks for letting me read your work,
C.R.
