Along with this, if you get the Red Lobster emails (sign up on their web site) they have recently sent out an email coupon for $4 off 2 dinner entrees or $3 off 2 lunch entrees.
Not a bad deal if you like what they are offering for the shrimp.
New Mango-Jalapeño Grilled Shrimp over wild rice pilaf
New Crunchy Parmesan Ranch Shrimp
Or you can get the good 'ole
Garlic Shrimp Scampi
Shrimp Linguini Alfredo
If you go this route, both of the new shrimp are pretty tasty, though I'm not a big mango fan so I'd personally not order them again. The Parmesan Ranch Shrimp should be eaten just seconds after the cool to the point they won't scorch your mouth. Don't let them cool, they aren't nearly as appetizing after sitting on your plate for a while.
But if you are asking me, I'd stay away from the promo and go with the simple but far better quality butterflied shrimp. 18 of those beauties and I'm in grease induced heaven.
