M and I came to check this out on a whim. I think M wanted to check out the virtual racing (which he did). I thought Rec Room was kind of tiny compared to D&B. I also find that D&B has a better variation of games. It's also a lot closer to home. Rec room also had some machines that were or of order and I found that it was really crowded and people were like on top of each other, even though there wasn't that many people.
Would I go back? I don't think so. It's too much of a trek to go for a place that's kind of mediocre.
