I was down in Portland and Seattle about 10 years ago ... there was a franchise called Wunderland. It was awesome! It was a massive arcarde; probably 125 games, maybe more.
You paid an admission fee of $2.95 (I think) and then all the games were a nickel after that. It was really good value... My friend and I proabably played in there for 6 hours one night and spent less than $10 each.
Edit: They still exist! Admission is still only $2 for adults.
