If you zero in on a venue where you have to avail of in-house catering, all you have to do is choose your menu according to how much you're willing to pay per guest (be sure to figure out your veg to non-veg ratio).
If, on the other hand, you need to book a catering service, you can choose between a buffet and a sit-down dinner, which cuisine(s) you want served and what will be on the menu.
If you're planning on serving up alcohol at your reception, you need to discuss whether the venue will take care of it or it will have to be ordered from outside (usually a cheaper option). You may have to pay a corkage fee at the venue so that you can bring in your own supply of alcohol. If possible, you can have your caterer supply the booze. But the most economical option is to bring your own bottles and have them served up, in spite of a corkage fee.
