Go Early or Wait
It is very busy for a chain restaurant, especially on Friday and Saturday nights. It's a big place, but if you get there during the rush (5:30 - 7:30) you can be waiting anywhere from 20 - 45 minutes. The food is great, but if I see people milling around outside, I tend to go down to Joey Basil's.
If you get in, try the seafood portafino (sp?) it's excellent.
