Guest does not eat onions, garlic, leeks, chilli peppers, fish (any type), curry, Japanese food of any type......what on earth shall I cook?

DD's godfather coming for dinner on Tuesday.
He is a really fussy bugger particular about food.

Any suggestions?
Any cheap suggestions, even better? Don't want to spend a King's ransom.

I've never been to a friends house for a meal, I don't really have any friends who have dinner parties and socialise mostly with family.
