When we would like a certain table/seat kept open for us at a restaurant, we usually call to make a "reservation". When you call, you would use either one of the above sentences when asked where you would like to sit.
1) I would like to reserve two seats at the bar, please.- this example is specific on how many people will be joining you at the bar.
2) I would like to reserve space at the bar.- This example is not specific on the number of seats and could be used when you are not sure how many friends will join you. When you say this, you could add on "for about 4 people". You use the word "about" to indicate that you are not entirely sure, but no more than 4 people would join you.
