Testimonials
-
Was wonderful experience. Kids loved it a lot spent at least 3 hours of fun with my two little ones. Pizza was good to and I like their service.
-
I love this place! It is a great price and lots of fun. It has really improved over the years and I've never been treated poorly. Tons of fun.

WE HAD A BLAST! The employees were super nice and informative, the food was great and the kids loved it! When comparing prices to other birthday party possibilities, Grand Slam beats 'em being soooo affordable with plenty to do. Things were in a neatly order and clean, which is a huge thing with me, mother of 3. We will be returning to Grand Slam in the near future and I just wanted to applaud this place as our experience was so terrific!

Just spent another fun afternoon at Grand Slam with out of town relatives. The pizza options are some of the best in the cities and birthday parties rock! So glad to have a place like Grand Slam where everyone can have a blast!

It was great! The kids (all boys 7 - 11 years old) LOVED it! I thought the place was clean, well managed, the areas seems to be in good repair and working. The food was surprisingly good (real meat hamburgers) and the price was comparable to any fast food place. The staff was VERY nice and accommodating.
-
Overall, kids love it, and it's a fantastic place to let them blow off steam when the weather outside is yucky.

We played mini-golf and the course was fun. I also got a pop after. Prices for most activities seem better than other places I have been and the food prices are a little high, but not crazy like a movie theater. I will be going back more!

We had so much fun. The owner is first class, pizza was delicious and service great. A great family fun day!

"It's hard to find a place both my 13 year old & 8 year old will like. I sit and read while they go burn off some energy. It's perfect. And they love the pizza!"
