True, the no tables inside sucks. However, the reason the lines were so long is because of the mass amount of locals that used to live in the Northeast. Most of those people that were in line were because they had been to and loved the wawa up north. It was like being home to them. I know, the 3rd one to open, opened near me and my husband was one of those in a long line on opening day. He couldn't wait to have a taste if home and everyone he talked to was like that.
As for this place, if cowfish had a 30 minute wait I am going to guess it was busy in general, so yes, the new place would have the longest line.
I will say I understand how many do not like the reservation system at Disney, but I wished Uni had a reservations system. I hate waiting to sit down and eat when I have had a long day at the park waiting in lines. I would love a one stop shop type of reservation system for Universal so I could book in advance and avoid the wait. We many times skip right by if all the places have long waits and just stop ad grab something on the way home.
