I've been able to actually get into Arsenal on ONE occasion. This place clearly is popular because each time we have tried to go during a time we think it will be less crowded, we are turned away at the door.
Despite this, when we did get in, we had an enjoyable experience. I went with a group for college night and played a few rounds for really cheap. The atmosphere is really laid back and gives you a "Big Lebowski" vibe. It's vintage and certainly is not a modern bowling lane. They have a bar in the back and the drink selection is decent. We had a great time bowling and made friends with the other groups around us as we did. Everyone was really relaxed and just there to have a good time. The staff were okay, as we had little interaction with them. It would be great if would could get back in again some time soon...
