How long is too long to wait for the "World's Greatest Pizza"?

My mother had been wanting to try this restaurant Pizzeria Bianco which she had read many rave reviews and had been wanting to try for a couple years. We had attempted to go a couple times, but after hearing the wait was four or more hours and even then we might not get to eat...we always ended up somewhere else. Last Saturday, we were determined to finally stick it out and wait. We arrived around 4:45, and had to wait about a half hour to put our name on the list. We were told that we would get inside around 9:25-9:45....OMG I think my dad is going to blow a gasper when he hears this news he was already complaining about being hungry. They told us we could leave but you have to call and check in every hour to keep your place on the list. We decided to go across the street and get some appetizers and drinks while we waited. I can't imagine waiting in the summer because the heat would just be too unbearable, but we enjoyed a nice cool but not too cold evening. Although we had a bit of a disaster with the cold or non-existent appetizers, we had a nice chat and enjoyed the atmosphere. Eventually we moved in front of the restaurant and chatted with the various other waiting guests. It seemed like every time someone would come and talk to us, that would ensure they would be soon let inside. Finally at 9:30 our name was called and we were able to go inside. By this time we were all starving and didn't need any time to decide what we were going to order. On a side note...my mom was all excited when she found out they had bottled coke and ordered a diet coke to find out that they only have coke because Chris Bianco, the owner, only drinks coke so he doesn't feel the need to stock any other options. We ordered four pizza's and were served quickly. I really liked the "Verde Bianco" and the other ones were pretty good too. All the pizza's are homemade by the owner and he makes each one personally. The restaurant itself is really small the capacity would be about 40 or 50 max. I really enjoyed the food, but not sure it was really worth the four and a half hour wait. I think next time I would get their a bit earlier and plan on making it a night. Plus I would have one person wait in line and the others grab a table inside the bar located next door because by the time we tried to get a table they were all gone. Plus make sure you have a late lunch so your not ready to eat your own hand...lol. And you can also ride the light rail so you don't have to pay for parking...another story altogether...or have to drive home after many bottles of wine.
