Your reservations are confirmed to cater your office party for Administrative Professionals Day on April 20. We appreciate City Councilman Bob Hopkins recommending our catering service to you.

We will serve the 225 office professionals at noon in the Roosevelt Dining Room located on the third floor of the Russell Building. The cost will be $10.50 per serving for the Japanese buffet.

Here's what I'd put:

Your reservations are confirmed to cater your office party for Administrative Professionals' Day on April 20. We appreciate City Councilman Bob Hopkins' recommending our catering service to you.

We will serve the 225 office professionals at noon in the Roosevelt Dining Room, located on the third floor of the Russell Building. The cost will be $10.50 per serving for the Japanese buffet.

I added 2 apostrophes and 1 comma. Do you see why?

(1) In the sentence, "We appreciate City Councilman Bob Hopkins recommending our catering service to you," there should not be a comma before or after "Bob Hopkins." However, there should be a comma after "per serving," as it is an interrupter phrase providing additional information.

(2) Yes, "Administrative Professionals Day" should be capitalized as it is a specific holiday or event.

(3) Regarding numbers and punctuation, the sentences appear to be correct. The number "225" is properly written, and there are no other punctuation mistakes.
