It is really hard to say. If you request a table for four, you may get one, but I am not sure that you can count on that. If you booked through a TA, then call and ask them to make this request. If you didn't book through a TA, then call DCL directly.
If you have a preference, call and ask for it. There are many tables for 4...there are also larger tables. Just call your TA and tell her to call DCL and put in a request for whatever you want.
