This is definitely a fun evening out for families but a bit on the pricey side. Do your research ahead of time to save money. Smoking is the biggest pain to deal with and second would be the bathrooms. We have a rule that everyone must use the bathroom BEFORE we leave our house and hopefully that will last them throughout.
On Dollar beer night it should also have dollar soft drinks, I am NOT a fan of having to spend more money to NOT drink than to be drinking alcohol.
The kids had a blast for the most part of the races but it can be a long evening and all 3 were ready to go halfway through.
All in all, you will have fun if you go on a night when you can save a good deal, eat ELSEWHERE, don't use the bathrooms!
