Review for Rideau Carleton Entertainment Centre and Raceway Review For Rideau Carleton Entertainment Centre and Raceway Google User May 7 '18 at 17:21 Rideau Carleton Raceway has a great buffet to enjoy, even when you aren't excited about the horseracing or casino. Sunday night is "Prime rib buffet" at $25 per person, and it is well worth it. Kids are allowed in on Sunday night until 10pm, but they have to enter through the "Family Entrance" in the back. Definitely a good time and a good meal. Be sure to make reservations. View full site to comment or like
