For how long the wait can be, I'm not impressed. I've been here four times; usually with groups of five or more. Grimaldi's was chosen because it was close to where we worked and pizza was a neutral choice. The wait is usually about 30 minutes.
Once seated, you feel a little cramped. There just seems to be to many tables for the space. You're close to climbing over people to get seated or leave.
As far as the food, it's fine but not particularly tasty or inspired. The sauces are on par with any other pizza place. The salads are a good size. When considering sandwiches, they are big but coated in the same lack luster sauce. Finally, if you're having pizza, you better be in the mood for thin crust which will tend to have a little extra char than you might like.
Considering the pizzas are priced per topping, I think (and my party) were most recently disappointed with the spread of toppings. At $2 per, I was just hoping for more meat than we were presented.
