Thanks for the info. Last week for Tmobile Tuesday they we were able to get free shakes from Shake Shack. There is 2 about 20 minutes away from me. I decided to give it a shot and it wasn’t bad. I mainly went for the free shake but bought a grilled cheese too. It was so good. I couldnt finish all the shake though. I also found another resurant next door to it called Bristols Seafood and Shrimp place. It’s pretty fancy but I have gift cards and gift certificate there. So Win Win!! Ohh and there is a Cheesecake Factory over there too so I can get my slices of cheesecake too!! Woohoo! Thanks Shannon for reminding me of this!
