I'm a bit taken aback with the comments that are less than perfect for Guido's. I have been going to this restaurant for seven years now and it was the first restaurant at which I ate when I considered moving here. I have held countless dinner parties at the restaurant and will be doing so again in just two days. Every aspect of every meal has been perfect from the service, to the impeccable food, to the excellent cocktails and wines. The portions are abundant and perfect for sharing if you want to save either money or your waistline. They always use the freshest ingredients. If it's not on the menu, the chef will do his best to make what you want. As for reservations, I would suggest you call in the spring and summer months when the tourists really descend on this little beach community, but in fall and winter you can just walk in. I have never seen people in beach attire, as it is a white table cloth establishment, but business casual is fine.
